Comment(by simonmar):

 It's tricky to know what to do about the subprocess in the event of an
 asynchronous exception.  Calling `waitForProcess` in the exception handler
 could be a bad choice, because the process might take a long time to
 terminate.  On the other hand, the context might not be expecting the
 subprocess to be still running if an exception is raised.  I'm not sure
 what to do here.
