Slow VCL speeds

[davejcb]

If I watch top, the oclhashcat process just consumes more and more memory, starting at ~15%, and steadily consumes until all is exhausted. The rate is about 2%/hr, if I remember correctly.

Not sure if it's VCL related or oclhashcat related- either way, I'm throwing in more RAM and restarting every so often as a cure for now.
