So I'm trying to get a handle on where exactly an mmapplypolicy that's
doing a premigrate is in its progress.  I've already determined that
'ltfsee info jobs' will only report where in the current batch it is,
but that still leaves me unable to tell the difference between

mmPolicy.chosnlist.97168.79FD2A24.pre. 10000 files dispatched.

and

[I] 2017-06-06 at 02:44:48.236 Executing file list: /gpfs/archive/config/tmp/
mmPolicy.chosnlist.97168.79FD2A24.pre. 225000 files dispatched.

Is there any better way to figure out where it is than writing the
cron job to launch it as

mmapplypolicy | tee /tmp/something

and then go scraping the messages? (And yes, I know not all chunks of 1,000
files are created equal.  Sometimes it's 1,000 C source files that total to
less than a megabyte, other times it's 1,000 streaming video files that total
to over a terabye - but even knowing it's 194,000 into 243,348 files is better
than what I have now...)
