This patch adds optional control flow in a pretty crufty way to *some*

certainly introduce bugs.
Amit plans to add support to the others as well. Beside that there is
a clearly defined backup plan: In case the non-blocking interface
isn't supported by $chardev it will fallback to use the blocking mode.
If we have a second interface, we'll have two interfaces forever. I'd
rather see us aggressive remove the blocking interface instead of
introducing a second interface.
I'm all for killing the blocking interface. Problem is that converting
over all users isn't exactly trivial and we have plenty of them. IMHO
it isn't realistic to do the switch with a single patch series.
cheers,
