Thanks for tracking this down.  I had a feeling that it was time 
dependent, and I had thought that it was because of the 
NSAutoreleasePool since that will screw up the stack.. but I guess that 
the worst it can do is make zombie objects, not free too many.

I'm pretty sure I've seen this bug before, intermittently, when writing 
inject plugins.  When I get some time I'll see if I can find out why 
it's happening, though that's obviously hard because I don't have 
access to the source code for Foundation :)
