Does CUDA has a proper done method?

Sayantan, are you available? To tell the truth, i did (really) small 
changes inside some of this files. But there are hard work to be done.

As I said before, to use it properly in my branch, i need a proper done 
method in all these files.

It will be nice if we can port DES, BF and MScash2 to use this new 
devices, platforms, ..., (from the new common-opencl.c), LWS, GWS.

> But I digress. This revealed that the problem you saw exist in unstable-jumbo too, so I did some more head-scratching and ended up realizing my last patch was the right way of handling it, but it did not support all kinds of systems. It does now, problem solved. No workarounds, just a correctly restarting signal handler.

Very good. Will try to merge it soon.
