Fix for potential hang when trying to reboot the system or
to forcibly unmount a soft update enabled filesystem.
FreeBSD already handled the reboot case differently, this is however a better
fix.

This looks like a big change but it isn't. It should reduce the size

the lock will be freed too early.
Without lock debug, libc_r should be smaller and slightly faster.
