[Benjamin Smedberg]

This bug as filed is INVALID. Bug 705154 looks like the hang detector malfunctioning on Mac. This bug looks like the hang detector functioning properly on Windows: each of the different crash signatures here needs its own bug and investigation.

To note: when the hang detector triggers, it is usually the stack from thread 0 that is interesting, not the stack from the hang detector thread, which is what the crash-stats UI currently shows. Note that the crash signature is properly created from thread 0.
