[3.12] gh-104372: Drop the GIL around the vfork() call. (GH-104782) (#104942)
gh-104372: Drop the GIL around the vfork() call. (GH-104782)
On Linux where the `subprocess` module can use the `vfork` syscall for
faster spawning, prevent the parent process from blocking other threads
by dropping the GIL while it waits for the vfork'ed child process `exec`
outcome. This prevents spawning a binary from a slow filesystem from
blocking the rest of the application.
Fixes GH-104372.
(cherry picked from commit d08679212d9af52dd074cd4a6abb440edb944c9c)
