Upon further investigation, this definitely seems a likely possibility on
Win32.  On Unix, the mtime will always have zero usecs (because it starts
out as a time_t and gets multiplied by APR_USEC_PER_SEC.  On Win32,
however, mtime comes in from the OS as a FILETIME, which could potentially
include a nonzero number of usecs.  Boom.
