 The progress dialog I use, along with the async task thing I cobbled
 together is still somewhat race prone and fragile, and sometimes leaves
 the dialog box up instead of hiding it.

 I mostly see this when testing on my VM.  The code in general could use an
 overhaul and cleanup since it's kind of kludged together.
