 /* errCatch - help catch errors so that errAborts aren't
  * fatal, and warn's don't necessarily get printed immediately. 
  * Note that error conditions caught this way will tend to
  * leak resources unless there are additional wrappers. 
  *
  * Typical usage is
  * errCatch = errCatchNew();
  * if (errCatchStart(errCatch))
  *     doFlakyStuff();
  * errCatchEnd(errCatch);
  * if (errCatch->gotError)
  *     warn("Flaky stuff failed: %s", errCatch->message->string);
  * errCatchFree(&errCatch); 
  * cleanupFlakyStuff();
