[PATCH] open conserver client connections in nonblocking mode

I recently tracked down a nasty conserver stall to the fact that conserver opens
connections to the console program and leaves the socket in blocking mode,
due to what looks like a silly typo.

The attached patch fixes that typo, and prevents the stall I was seeing from
happening.
