-Subject: [PATCH] Use umask() to Constrain Created File Permissions
-
-This commit addresses #2491.
-
-Note that a downside of this solution is that it is global: `umask()` affects
-all file creation calls in the process. I believe this is safe since
-`fileio.c` functions should only ever be used in the zstd binary, and these
-are (almost) the only files ever created by zstd, and AIUI they're only
-created in a single thread. So we can get away with messing with global state.
-
-Note that this doesn't change the permissions of files created by `dibio.c`.
-I'm not sure what those should be...
