+- Issue #21618: The subprocess module could fail to close open fds that were
+  inherited by the calling process and already higher than POSIX resource
+  limits would otherwise allow.  On systems with a functioning /proc/self/fd
+  or /dev/fd interface the max is now ignored and all fds are closed.
