I have one question.

Been trying to solo-mine bfgminer -> bitcoind, but bfgminer keeps working on old stuff way after the block has changed.

How can I use blocknotify of bitcoind to tell bfgminer to actually pick up the new block and new work ?
With eloipool in between, all works fine, but it is overkill, and it eats 100% CPU on one core.

Any SIGxxx to send ? Something else ?
