I've just noticed a strange behaviour in devpipe that occurs on both
9front and Plan 9.

When the write blocks, if a note interrupt the process, the waserror
in pipewrite and pipebwrite will post another note that says "sys:
write on a closed pipe ..."

However the pipe is actually open, and still works, as you can see in
the attached test.

Shouldn't the waserror code check that the queue has been actually closed?
