Using zmq is a great fi= t for high-speed notifications such as this. Have you seen the pull request= to integrate zmq directly into bitcoind, so that you don't even need -= blocknotify?

https://github= .com/bitcoin/bitcoin/pull/2415

If not: we could use some t= esting there!

As others have said, queuing outside of bitcoind is a better approach= .
I use zeromq for this situation. blocknotify runs a program which uses
zeromq's pub/sub to queue and the application subscribes to this to
get notified of the data.
