Description

Starting impalad with -logbufsecs 0 makes it spin in the thread that tries to delete old logfiles.

tarmstrong, henryr - Is this intended? If not, one fix would be to sleep for std::max(1, FLAGS_logbufsecs) in LogMaintenanceThread(). Another option would be to require a value >0 for logbufsecs.
