	For some reason, the system will sometimes crash when unloading the
driver. The cause is always "page fault in kernal". Syncing the disk appears
to prevent crashes, although I don't understand why. I have had good luck
using the following command sequence to unload the driver.

	# cd /etc/lddrv
	# sync;
	# sync
	# sync
	# ./lddrv -d uipc

If anyone can shed light on why this works, I would love to hear it.
