Could you expound a bit?  That’s a very short summary for all the sweat
you’ve put in it.  :-)

Also, what is the patch against?  It’s not against ‘master’; I suppose
it’s against the previous state of your own branch, do you have a copy
of your repo on-line?

It’s OK that the thing doesn’t quite work—we knew it was not an easy
task.  What’s disappointing though is that you didn’t come to us to
discuss the issues until now.  GSoC is not about working in all
loneliness separately from the rest of the group; it’s about becoming
part of the group.

On IRC Jelle and I (and possibly others) offered help on the ‘signalfd’
issue; I also outlined reasonable milestones (first, only use
signalfd(2) instead of SIGCHLD, then discuss together what it would take
to Fiberize the whole thing.)  It’s sad that you remained stuck instead
of taking this opportunity to discuss it with us.

The patch changes lots of things and unfortunately, without
explanations, I do not understand what to do with it.  Like what’s the
new feature?  How is it used?  What implementation choices were made?
What’s left to be done?…

Thank you,
Ludo’.
