Aaaahhhh... this is really not great for server/Sun-ray deployment, we
will have servers that are running maybe hundreds of desktops.  But we
know that unless we are developers who are constantly building stuff,
our CPUs are idle most of the time...

Server-side environments like SunRay take advantage of this fact but
this doesn't work so well if everybody's "idle" desktop is constantly
pinging filesystems.  My gut tells me that this could degrade the
maximum number of desktops that could be served by a machine
appreciably.

Keep in mind that this is exactly one of the settings where
GNOME/linux has an advantage over the so-called "leading" consumer
desktop ;-), in libraries, schools, and businesses who "hot desk".

So it's not really "cost-free"...  one ping every now and then might
not be as bad (though it will still keep things from swapping out as
you'd like them to) but multiple I/O ops in an otherwise idle apps are
not so nice.

Best regards,
