[Redis] DEV release with new network code

[Damien Krotkine]

Hi,

I've juste released Redis-1.973_01, it's a DEV release with the new
network code from Ivan. Basically it now uses sysread instead of
readline. I hope cpantesters results will be good enough.

If you have the opportunity, please install this version and test it,
especially in situation where latency and/or speed performance is
needed, as I would like to make sure the performances are the same or
better, before releasing a real version

Thanks,
dams.
