Gregory, shall we close this JIRA for gc.LOS?  I am out of context
about its status. Now gc.LOS should have no problem to pass in our
tests, but this JIRA says it only fails in WinXP.

The bug which caused hangup on windows XP (and windows 2003 without SP1) 
used to be because windows kernel didn't allow parallel execution of VEH 
handler (note that the test contains code which causes hardware NPE). 
This bug has been fixed a while ago and should not be reproducible any more.

I think we can close this issue because gc.LOS is not excluded on 
windows32 any more. I am closing this issue as won't fix because the 
test won't be included into acceptance tests since it is a part of 
gc.LOS which is already present in acceptance tests.
