The heartbeat test takes place in the interpacket gap.  The window
for the test is between 4 and 8 microseconds after the Sun finishes
each packet.  If Suns were to violate the spec and shorten the
interpacket gap, the net news would be full of complaints that
Suns don't work with IEEE transceivers.  This is not the case.
