I don't know if its still the case, but when I was playing with venti
a few years ago it had problems with chunks of memory > 2G. I was
trying to run p9p venti on a sever with 64GB of RAM but could only use
a fraction of that for the venti caches. Now that may have been more
of a venti problem than a p9p problem, sadly I didn't have the time to
track it down.
