Hi all,

I've got a -current box freshly CVSup'd and built from last
night that is exhibiting some rather bizarre behavior.  I
actually noticed the problem on my Alpha package building
machine, but the same behavior exists on my i386 box.

To see what I'm seeing (or maybe not :) all you have to do
is this:

	cd /usr/ports/graphics/jpeg
	make extract

The gzip(1) process is hanging in pipdwt.  I run the equivalent
commands from the commandline and it works fine.  I 'kill -6'd
the offending process and this is what the stack trace looks
like.

(gdb) bt

Can anyone confirm this happens on their box?  Anyone have any
ideas on how to go about fixing this?

Thanks.
