In fact, cygwin goes to great lengths to work around this bug in the MVFS
file system (that is, duplicate the handle, set atime on the duplicate,
close it to force a flush to disk, then set atime on the original).  Which
file system was the libarchive bug reported on?  Maybe we need to reuse
the MVFS hack on other file systems.  But my experience has been that
futimes works correctly on NTFS.

Don't work too hard, make some time for fun as well!
