I've tried to change the code so that an autoreleasepool in the process 
of being deallocated remains present as the current autorelease pool 
(if it was the current pool), while still making sure that objects 
added to it while it is being deallocated do not get leaked.

I can't see why there should be any odd thread related problems ... 
unless it's to do with the current pool for the thread being 
deallocated on thread termination, and objects added to the pool during 
deallocation, which would previously have been quietly leaked, causing 
a problem in some way.

Please try the current code from CVS and see if it still causes 
problems ... if it does, please could you try to find a sequence of 
operations in GWorkspace which reliably cause the problem ... I'm not 
familiar with what might cause threading problems in the app ... so the 
fact that it's working for me might just be that I'm not trying out the 
correct sequence of operations.
