My build was running really really slow.  Bumping the heap and permgen 
for surefire seemed to fix the problem.  Its probably either the server 
starting/stopping so much and not fully cleaning itself up after a stop, 
and/or we have a lot of open JAX-RS clients Apache Http Clients that 
aren't being closed from our tests, and/or selenium doesn't clean itself 
up nicely.  Something we might want to look into later.
