           Summary: [Regression] Crashes in threading code after update to

This commit seems to have causes a regression:

================
r89306 | mprobst | 2007-11-09 10:37:12 +0100 (Fri, 09 Nov 2007) | 14 lines

2007-11-09  Mark Probst  <mark.probst at gmail.com>

        * gc.c, gc-internal.h: Don't finalize threadpool threads with
        other objects, because the threadpool is still around.  Put them
        in a list instead and after finalizing all other objects in the
        root domain shut down the thread pool and then finalize the
        threads.  Fixes bug #337383.

        * threads.c, thread-types.h: New mono_thread_create_internal()
        function for marking a thread with the threadpool flag before it
        started.  Set synch_cs to NULL after freeing it.

        * threadpool.c: Mark threadpool threads before they start.
================

After updating to r89306, Mono crashes after several hours of usage (Apache
running several ASP.NET sites with medium traffic). I have no idea how to
reproduce the crashes any faster. Reverting this commit "solves" the problem
for us.

This is written to Apache's log:
