    Description

      Occasionally we need to capture the state of all threads for performance analysis.
      Currently this requires installing `gdb` and running an external script.

      I propose implementing a signal handler calling printStackTrace().

      This would ease diagnostics as we can achieve the same result by issuing a kill signal.
