Content
The safe_get_max_fd() (in Modules/_posixsubprocess.c) is documented to be async-signal-safe. However, this function calls sysconf(). sysconf() was guaranteed to be async-singal-safe in SUSv3, but it's no longer in SUSv4. I don't think it's going to be a problem in practice, but it's probably worth adding a clarification comment.
