look closer. openbsd's "touch page" times are identical to what you'd
expect a disk access to be. the pages aren't cached, they're read from
disk. so compared to systems that don't read from disk, it looks pretty
bad. a 5 line patch to fix the benchmark so that the file actually is
cached on openbsd results in performance much in line with freebsd/linux.
