Think about it simply. A cell gets deallocated just like any other object -
when its retain count goes to zero. If you're looking for a cell getting
deallocated on a non-main thread, you're looking for a place release is being
called on a non-main thread. I would think you could just override the dealloc
method to help you track this situation in the debugger. Perhaps add an
NSAssert([NSThread isMainThread], @"wups"); in there.
