assert (! __spin_lock_locked (&ss->critical_section_lock));

[Samuel Thibault]

Hello,

Antrik got

ext2fs.static: thread-cancel.c:55: hurd_thread_cancel: Assertion `! 
__spin_lock_locked (&ss->critical_section_lock)' failed.

And I wonder why we do this.  Are we supposed, when calling
hurd_thread_cancel, to be sure that the target thread is not in critical
section?
