- Fix a major problem in pushlock implementation: if there are 2 or more
threads waiting for a lock, only one of them ever gets woken. ExfWakePushLock
is missing a break in its loop so it removes all the WaitBlocks instead of just
the last one.
- This fixes all "weird" hangs happening, including FF1.5 installer hang, VMWare Video Driver Installer hang, taskmgr tabs hang, and other similar problems.
See issue #3141 for more details.
