NSNetService gotcha

(Cross-posting from my weblog

some debugging time.)

If you're using NSNetService to publish a service via Rendezvous,
don't use the following code to stop the service:

  [myService stop];
  [myService release];
  myService = nil;

You'll fail miserably with a bus error inside of Rendezvous, with no
direct evidence why it happened.

It turns out that there's teardown that's still happening after -stop
returns.  So you need to set a delegate for your service, and release
& nil out the service in the delegate method -netServiceDidStop:.

The PictureSharing sample does, of course do it the right way.  I was
just skimming the documentation and coding away...
