Message:

Adding threading for pmSubtractionConvolve. This was more difficult than for the others because the threads are working on a common image. Turns out that making child images using psImageSubset is not thread-safe: the image (which all threads are using) is modified. Wrapped those calls up in mutexes, and now threading seems to work fine.
