On Linux you'd do this by sending a signal to the thread you want to analyze, and then the signal handler would take the stack trace and send it back to the watchdog.
The tricky part is ensuring that the signal handler code is async-signal-safe (which pretty much boils down to "ensure you're not acquiring any locks and be careful about reentrant code"), but at least that only has to be verified for a self-contained small function.

Is there anything similar to signals on Windows?
