Woah, I definitely didnt get things sent out, sorry about that Pete.

It's a very crude code for right now, and there are some obvious issues 
with it, but it causes the hangs quite reproducibly.
There may be a hardcode that I thought I had patched, and not ever 
exactly patched in the Makefile for the pvfs2 headers.

Give it a try, it should break something, thats for sure.
