--------------------------------------------
this doesnt apply cleanly to stack_iterator_ia32.cpp - does that surprise you?

> Earlier, exception/signal handler returned control to interrupted code during JIT breakpoint processing, so it restored all unmodified processor registers including processor flags.
> Now control is returned to interrupted code directly from breakpoint handler using si_transfer_control function. This function restores general processor registers, but it does not restore processor flags modified during breakpoint processing.
