The mailbox is unresponsive because ViewPort.isbusy is being set to  
true, but the code is crashing before it can be set back to false.   
Thus all other calls to ViewPort are entering infinite loops because  
they are waiting isbusy to return to being false.

I've hesitated putting try/catch() statements around these calls  
because it may leave the viewport in an incorrect state and, IIRC,  
errors in the try/catch statement will not bubble up to tools like  
firebug.  Although in the latter case, I think that we can re-throw  
the exception and this will fix that issue.

But the underlying issue needs to be debugged on the server where it  
is seen.  So you'll have to catch this in the future and poke around  
to discover the issue.
