Subject: --fork using different OpenCL devices

Claudio had an idea a while ago that I think still hasn't been discussed on list so here goes:

The idea is to have -fork pick a different device (starting from 0 or picking from a given list) for each child. Picture having two 7990 cards for a total of four devices. Using "-fork=4" with an OpenCL format would pick device 0 for the mother process, device 1 for first child and so on. Only very fast formats [where set_key() is a bottleneck] would benefit.

I think it's a cool idea and Claudio has a trivial PoC patch. Should we do this? It will hopefully be obsoleted by mask mode and other planned things. OTOH I would not mind at all applying it.

Any comments are welcome.
