Hmm... I was considering the costs and benefits of sync mounts.  I don't
care about the performance hit, as I don't move that much data around.
Primarily, I like the fact that I can pull the media out w/o any special
action (which sometimes requires that I unlock my screensaver first).
But, on the other hand, it's nice to have the media last longer.

So, maybe it would be a good idea to have a 'delaysync=60' to force a
sync after 60 seconds of inactivity.  Unless, there is something else
that would do that for me already.

Thoughts?
