Sometimes windows will send us events about breakpoints we have already removed from the code despite the fact that we go to great lengths to avoid this already. Change waitForDebugEvent to check that when we receive a breakpoint event the corresponding memory actually contains an INT 3 instruction, if it doesn't ignore the event and restart the thread.
