this f'ing code has a Heisenbug.

This is like trying to disect a jellyfish with a spoon. I'm giving up for the day.

Race conditions in multi-threaded systems too, they can be extremely sensitive to timing variations (and debugging output may well cause a context switch). And bugs tied to the message queue in Win32 - sometimes any additional instrumentation ties into the message queue itself and can radically change the symptoms.

Ah yes -- I so rarely work with things where timing is important that I forget that type of particularly nasty bug. Icky.

Debugging Parallel programs? Someone ought to do some research on that, a PHD even...
