just fyi, the burn on mmap is because it's going to disk.  without ubc, if 
you unmap the page it disappears.  so the next mmap has to go disk again.
problematic, but most webservers don't engage in such mindless behavior.
it's unclear what current he tried, and if it had random mmap in it, 
but the cost of randomization is not nearly so bad. :)
