On a Sun (and presumably under bsd 4.x as well) there's a usleep()
function to sleep for a specified number of microseconds:

	void usleep(useconds)
	unsigned useconds;

This actually pauses for _at least_ the specified number of useconds.
The actual delay may be longer depending on other activity in the
system.
