Update.
2002-12-13  Ulrich Drepper  <drepper@redhat.com>

	* misc/syslog.c (log_cleanup): Don't use parameter in
	__libc_lock_unlock call, use syslog_lock directly.  Adjust callers to
	pass NULL instead of a pointer to syslog_lock.

-/* This function is responsible for calling all registered cleanup
-   handlers and then terminate the thread.  This includes dellocating
-   the thread-specific data.  The implementation is complicated by the
-   fact that we have to handle to cancellation handler registration
-   methods: exceptions using try/finally and setjmp.
-
-   The setjmp method is always available.  The user might compile some
-   code which uses this method because no modern compiler is
-   available.  So we have to handle these first since we cannot call
-   the cleanup handlers if the stack frames are gone.  At the same
-   time this opens a hole for the register exception handler blocks
-   since now they might be in danger of using an overwritten stack
-   frame.  The advise is to only use new or only old style cancellation
-   handling.  */
