- Prevent kernel bug check in win32k when calling a hook proc when thread is in cleanup.

- This is not a hack and not a fix. Please retest related bug report applications. Tested Firefox 3.5 and the new putty. Need new debug print outs. ATM Ff 3.5 send out WH_JOURNALRECORD hook calls when the thread is in cleanup. Look like this: Thread is in cleanup and trying to call hook 0
- Reference bug 4298.
