+
+The most annoying part of this bug is that though I've found it in two separate apps, I don't have a trivial testcase for it.
+
+The problem seems to be a condition race, as it's triggered quite randomly (therefore it will be hard to tell whether it really gets fixed, if a probable fix is found).
+
+While it's specific to SDL 1.2, it seems quite similar to the problem described and fixed in http://forums.libsdl.org/viewtopic.php?p=40503.
+
+Now, I should start describing the problem.
+
+A game uses Escape to open menu (the exact key might not be important). Upon opening, it calls SDL_EnableUNICODE(1). Upon closing it calls SDL_EnableUNICODE(0).
+
+I have an IME running.
+
+Game uses SDL_PollEvent to get the events.
+
+If Escape is pressed repeatedly, menu is opened and closed, till it eventually freezes in open state.
+"freezes" in this context means "app itself still runs, but no keyboard events are getting delivered (though - for example - mouse events still are)". "getting delivered" should mean "SDL_PollEvent is not receiving any".
+If it matters, the last delivered keyboard event is a keypress, the release never arrives.
+
+It seems (no guarantees, due to random nature of the freeze) that unsetting XMODIFIERS (which - AFAIU - will disable IME as far as SDL is concerned) prevents the freeze, therefore the reference to that SDL2 thread.

+.TH sdl-config 1 "2013-06-19" "SDL 1.2"
+.SH NAME
+sdl-config \- script to get information about the installed version of SDL
+.SH SYNOPSIS
+\fBsdl-config
+[\~--prefix[=\fIDIR\fP]\~]
+[\~--exec-prefix[=\fIDIR\fP]\~]
+[\~--version\~] [\~--cflags\~] [\~--libs\~] [\~--static-libs\~]\fR
+.SH DESCRIPTION
+.B sdl-config
+is a tool that is used to configure and determine the compiler and linker
+flags that should be used to compile and link programs, and libraries, and
+plugins that use SDL.  It is also used internally by the m4 macros that are
+included with SDL.
+.SH OPTIONS
+.TP
+.B --cflags
+Print the compiler flags that are necessary to compile a program or library
+that uses SDL.
+.TP
+.BI --exec-prefix= DIR
+If specified, use
+.I DIR
+instead of the installation exec prefix that SDL was build with when computing
+the output for the --exec-prefix option. This option must be specified before
+any of the --cflags, and --libs options.
+.TP
+.B --libs
+Print the linker flags that are necessary to link a program that uses SDL.
+.TP
+.BI --prefix= DIR
+If specified, use DIR instead of the installation prefix that SDL was built
+with when computing the output for the --prefix, and --exec-prefix options.
+This option is also used for the exec prefix if --exec-prefix was not
+specified. This option must be specified before any of the --cflags, and
+--libs options.
+.TP
+.B --static-libs
+Print the linker flags that are necessary to statically link a program that uses SDL.
+.TP
+.B --version
+Prints the currently installed version of SDL on standard output.
+.SH EXAMPLES
+.TP
+gcc -o main.o $(sdl-config --cflags) main.c
+is how you might use
+.B sdl-config
+to compile a C source file for an executable program.
+.TP
+gcc -o my_app $(sdl-config --libs) main.o util.o
+is how you might use
+.B sdl-config
+to link compiled objects into an executable program.

+Correct vec_perm() application on little-endian 64-bit PowerPC
+
+The LE transformation for vec_perm has an implicit assumption that the
+permutation is being used to reorder vector elements (in this case 4-byte
+integer word elements), not to reorder bytes within those elements.  Although
+this is legal behavior, it is not anticipated by the transformation performed
+by the compilers.
+
+This causes pygame-1.9.1 test failure on PPC64LE because blitted pixmaps are
