-----------------------------------------------------------------
I agree with [~rajesh.balamohan] suggestion to pass on null for thread pool in
recursive call. It will mean parallelism will be limited to number of distinct
dirs in first level, but that will be better than single threaded execution as
well as hangs.
[~pxiong] What do you think?
