Instead of cutting/pasting sections here see
http://dabbs.net/reiser4/mongopl.html. I have annotated my modifications to
mongo's mount handling with 'dmd.' There are other non-annotated changes I
have made, but they are not germane to this issue. If you want to know
exactly what is different, diff this with the mongo.pl in the build Elena
recently uploaded at 
http://thebsh.namesys.com/benchmarks/mongo-2004.07.26.tar.gz.

I'm still rerunning tests to see if I can reproduce, but time is limited
this weekend.
