Only in 4.3BSD and later (4.2BSD just gave back 10 ms. increments), and
only where the hardware supports it.  The routine `microtime' in
/sys/machine/machdep.c is responsible for determining a more accurate
time.  On most Vaxen this is indeed done this way, but the MicroVax II
does not have the register.
