[Python-Dev] Release or not release the GIL (original) (raw)

dup2(oldfd, newfd) closes oldfd. No, it doesn't close oldfd. It may close newfd if it was already open.

(I guess that's what he meant).

Anyway, only dup2() should probably release the GIL.

One reasonable heuristic is to check the man page: if the syscall can return EINTR, then the GIL should be released.
