I haven't done any exhaustive research into this topic, but this is what 
I've observed, along with my speculative conclusions:

1) When the last request to WEBrick results in an exception, I can 
shutdown WEBrick and it terminates quite snappily.

2) When the last request to WEBrick is successful (with no raised 
exception), WEBrick can take up to a minute to actually terminate.

I *suspect* that this has something to do with the browser keeping the 
connection to WEBrick alive. Perhaps WEBrick can't shut down as long as 
there is an active connection, and it has to wait for that connection to 
time out? Can anyone comment on how feasible this might be?
