My public changes are available at
https://bitbucket.org/tkoskine/not-claw-sockets-linux-x86

Don't be fooled by the repository name, the code works (barely) only
on x86_64 (not on i386).

And while I remember, I think I hacked select so that it works with only
one socket at time... (It is quite hard to create a binding to select(2),
especially if you want it to work on multiple architectures without code
changes.)
