This isn't convincing that there's a memory leak.
Maybe you've just had more simultaneous messages
outstanding than acme connections. I on the other
hand run a lot of wins all the time, so my acme 9pserve is
bigger.

I tried to reproduce this using plumber but can't find anything:

; mkdir $NAMESPACE
; @{rfork s; plumber >/dev/null >[2=1]}
; fn z {psu -a|grep 9pserve |grep /tmp/xxx}

Those errors are odd, of course, but not a memory leak.

That's not it. q->hungup is always zero. (Good thing, too,
since no one looks at the return value of sendq.) I should
clean that up.
