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

Either that or check errstr against Ehungup, since that's the exact error it incurred.

The latter has the advantage of not obscuring a different error if the pipe is closed

between the write and waserror, but with pipes there's not much except interrupt, I suppose,

so it seems a minor race and perhaps the qclosed check is adequate.
