> Synchronization with Tablet$Scanner via a read() will block close() being called via
the sweep method in TabletServer. As a result, the SimpleTimer thread does not continue, and
idle threads grow until the scan completes. 
> My patch, which is forthcoming, converts synchronized methods to use a fair lock. If
the lock is held by a read call, the close call will attempt to obtain it, time out, and return
indicating a close was not successful. The sweep will continue, and the SimpleTimer thread
will respawn later, attempting closure on those Tablets at a later time.
