There is no one-second-interrupt but a one-second-timeout (see timeout.c,
function checkalarms).  The timestamps have to be updated once a second
(actually only every 2nd second) because file system drivers (notably
the kernel's process and pipe file system) rely on that behavior.
Currently Petr's ideas wouldn't mean any performance loss.

What if everything is an illusion and nothing exists?  In that case, I
definitely overpaid for my carpet.
