Upgrade to 0.8.5 or commit 5ca5a69b needed by February 20

[Forrest Voight]

Hi, all. This is the first message on the P2Pool notifications group.
Thanks for signing up!

On February 20th, all Bitcoin clients will switch to using checksums
when they initially connect to peers, as further explained in [1].
This will affect P2Pool because the p2pool daemon makes a local P2P
connection to bitcoind in order to listen for new blocks.

I didn't know about this until about three weeks ago, so P2Pool only
had support after this commit:

commit 582d6eac0e6a4e0058afddfd232b27824da0fe38
Author: Forrest Voight <for...@forre.st>
Date: Fri Feb 10 12:47:23 2012 -0500

always use checksum in bitcoin p2p communications after
1329696000. thanks to gmaxwell for saving p2pool!

Please upgrade P2Pool to version 0.8.5 or a newer commit from git.
Un-upgraded P2Pool nodes will freeze on startup at this point:

2012-02-17 16:11:36.868416 Testing bitcoind P2P connection to
'127.0.0.1:8333'...

Thank you!
