[gnet-dev] zero-copy interface?

[Jeff Garzik <jgarzik pobox com>]

Being a GLib fan (and contributor, in years past), I naturally was 
interested in using GNet for a networking project of mine.

However, a showstopper problem for me is the amount of data copying that 
occurs in GNet, which really impacts CPU usage in my application.

I'm interested in modifying GNet as follows, in [my] priority order:

* figure out how to send integrate sendfile(2) support.  I see its in 
the TODO.
* figure out some way for app to provide buffer for async write, rather 
than having GNet memdup it
* figure out some way for app to provide buffer for async read, rather 
than having GNet allocate and manage it

Has anybody done any coding in this direction yet?
