I just realised that this behaviour may not be GC safe -- JSC is a conservative collector: at gc time we perform a conservative sweep of all machine stacks for references to GC objects.  By hoisting execution of the OS stack it seems that you would put JSC into a state where at least one set of roots can be missed.

How do you avoid this problem?
