	To my knowledge, not so: please see kern/86427.  This puppy
will choke my -CURRENT system in around ten days under a light
network load.  Under substantial traffic, less than three.
	I had hoped the network stack changes Robert Watson committed a
while back would fix this, but apparently not.
	This is a _major_ pain in the ass, and I look forward to the day
when someone drives a backtrace through its pulsing green heart.
