> The batch scanner has a threadpool.  When the batch scanner is closed it calls shutdownNow()
on this threadpool, which interrupts all of the threads.  If a user does not read all data
from a batch scanner and calls close, thens its likely that the background threads are still
busy and will be interrupted.  This is a normal course of business, so there is no need to
log an exception for these interrupted excpetions.  Some places in the code do log an error
when these exceptions occur.  
> One place is where the background code calls UtilWaitThread.sleep().  There may be other
places.
