> When the TT kills tasks that haven't reported status, it should somehow
> gather a stack dump for the task. This could be done either by sending a
> SIGQUIT (so the dump ends up in stdout) or perhaps something like JDI to
> gather the stack directly from Java. This may be somewhat tricky since the
> child may be running as another user (so the SIGQUIT would have to go through
> LinuxTaskController). This feature would make debugging these kinds of
> failures much easier, especially if we could somehow get it into the
> TaskDiagnostic message
