I wrote a packet traffic/protocol simulator where a 250Hz
clock (seemed to be the default on Linux) was not fast enough.
On FreeBSD I could just up the clock to 10Khz.  RTT
computation as Erik pointed out.  If you want to minimize
latency in usermode drivers and deal with simple(r) hardware.

Lots of uses.
