    That does look simpler, and avoiding the lock is a good idea. Since we
    don't support lseek() (or pread/pwrite) on that thing anyway, there's
    no way to keep the fd open and just re-use it to read the data over
    and over, so populating it at open time sounds like a good solution
    with no real downsides.
