 - Added a special checks for large files.  I've been seeing a
   system crash followed by a reboot that seems to corrupt the swap
   log.  Squid believes that the disk holds some really large files.
   It complains about using being over the high water mark and
   proceeds to delete files as fast as it can.  To prevent that,
   we call stat() on sufficiently large files (>128KB) and reject
   those that are missing or have the wrong size.
