      In SERVER-91012 we found that startSignalProcessingThread() is called in mongod_main.cpp, which does not run for unittests. Therefore, sigTid == -1, so we couldn't call terminateThread in stacktrace_threads.cpp, so the system deadlocks.

      We should invariant() that the signal processing thread is started in printAllThreadStacksBlocking() to avoid a deadlock.
