code looks ok, not sure what happened, pretty sure i lost my logs after the hmaster died,
but maybe i misread. need to repro.

> During recovery, the master had opened all the logfiles, but when it went to open the
destination files, it crashed.  The logfile is missing, the edits did not get applied.
> looks like there is a hole whereby we delete the original logfiles before we confirm
the new output logs were written. oops!
