I don't believe this can be a valid argument because high round zombie players
play this game literally for 7days + straight on PC and at a leak rate of about
2 handles per second (3500 handles in 35 minutes) that would result in 1.2M
handles the system would have to make space for.  I don't think a bug like this
could ever make it through QA on a triple A cross platform title.  The
+file,+ntdll log is monstrous and has balanced LZOpens and LZCloses, but I see
no closes for any of the huge number of FILE_Createfiles (way too many to
explain only 2 leaks per second).  Any clues as to what to look for to detect
the leak?  I might be able to trace the anomaly given I know its rate (slightly
less than 2 per sec) but it would help a lot if I knew what to look for in the
log.
