Hi Lena, 

PHASE_MKDIRS and PHASE_MKFILES were attempts on my part to inject some
realistic filesystem noise into the mongo tests. I simply listed all the
directories / files on my computer into files. I created two new programs,
mongo_mkfiles and mongo_mkdirs that read a list from stdin and create each
directory or file (zero length). I disabled these phases in the runs I
published as my test disk space is limited and I didn't want to muddy the
waters with non-standard mongo settings. I'll be happy to send you the
sources later today. Since the phases were disabled, essentially the results
were generated by 'standard' mongo (well, the cpu_util version) sources.

By the way, great work on finding the patch that had been slowing things
down.
