That's actually what I'm doing at the moment, calling listen(), then fork().
Each child adds a callback for EV_READ on the socket and runs its event
loop.
It tries to accept() on it when the callback function is executed, and
handles the client. This has been tested quite heavily without problem...
Could there be one?

Thank you for your precisions. I don't have an event loop in the parent, so
this is not a problem.

this was my main question... Is it possible to give evhttp a bound socket to
monitor?
I checked http.c but couldn't find any exported function doing this. If this
isn't implemented, would it be OK to submit a patch to add this feature?

Thanks,

Nicolas
