[postmodern-devel] the reason why i'd like an iolib network backend instead of usocket

[Marijn Haverbeke]

Hey Attila,

I've never seen this particular mess, but having low-overhead socket
timeouts would be very useful for most 'serious' projects, and if you
can some up with a patch that doesn't create too much of a chaos in
the codebase, I'd certainly be happy to include it.

Cheers,
Marijn
