Grr... I knew my idea wouldn't work. Hmm....

Well, a variation on the SVN one...
hg up would:
  * grab the time stamp now.
  * up date the files, setting the time stamp to the timestamp above.
  * wait till the time is timestamp+1.1 seconds (like SVN does).

Annoying, I know.  If you do updates on a hundred different
repositories, then it'll take over 100 seconds, even though it could
be done in less time.

The only other thing I can think of is add a switch to do the above
hack.  It would have to be carefully documented to explain what's up.

Unfortunately, we'll also have to add a flag to check some sort of
checksum incase someone does modify a file so that it doesn't change
that it can be found and dealt with.

Ciao!
