Can you be more specific, why setting HWM to 1 is a bad thing? Do you
mean, that it smells bad to set HWM to 1 for reliability? Or do you
think that setting it will have other consequences? (low performance?)

(I'm asking that because we are discussing an issue of setting HWM to
1 always in crossroads-io, which is zeromq fork)
