	Is this still true, and what was the problem so I can
	see if we think it's fixed?

	I have a bug report fixed in '94  that EPIPE might not 
	be delivered, causing the machine to spin forever, and
	another about disconnected sockets misbehaving in 2.5.1
	I wonder if it the bug is one we fixed in a later release.

	If so, we might be able to phase out the workaround over
	time. I can arrange to test on Solaris 6 through pre-alpha 
	9 if that would help.
