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.
