druntime commit, revision 487


user: sean

msg:
Made a few more changes (explained in comments) to deal with deadlocks and other bad behavior caused by badly timed collections.  This new approach works for the test code in bugzilla 4890, plus the other test cases I've found to cause similar problems.
