Dave, Serge:

I'm currently away so I must keep this short. I think we have so far
more discussion than an actual problem. I'm happy to coordinate with
every interested party to eventually see this work go into main stream.

My only concerns are twofold: first, to get more feedback I believe we
need to get the code a bit more usable; including FDs is an excellent
way to actually do that. That will add significant value to the patch.
I think it's important to demonstrate how shared resources and multiple
processes are handled. FDs demonstrate the former (with a fixed version
of the recent patchset - I will post soon). The latter will increase
the size of the patchset significantly, so perhaps can indeed wait for

It should not be hard for me to add functionality on top of a more
basic patchset. The question is, what is "basic" ?  Anyway, I will be
back towards the end of the week. Let's try to discuss this over IRC
then (e.g. Friday afternoon ?).
