To get the feature to the mainline, we'll need non-busy-waiting version 
of it. (Note that there's no busy waiting anywhere in 0MQ.)

The actual implementation would be presumably platform specific, 
however, there's a common mechanism that we can always fallback to.

Namely, we can poll (or select on win32 and openvms) on the single file 
descriptor. The poll (or select) luckily has a timeout parameter we can 
use to get the behaviour we want.
