In fixing the problem with GroupDetectors (above), it became apparent that the most-recently-used list utilised in ManagedWorkspace2D is not behaving as expected. When grouping, you loop over a load of spectra adding them into one spectrum. Yet that one spectrum, which is called every time you go through the loop, can still drop off the bottom of the list (and out of memory) - which it shouldn't.
Also, when running DiffractionFocussing, ManagedWorkspace appeared to be reading in from file far more than I would instinctively expect it to - something to investigate further.
Incidentally, the specific problem in GroupDetectors was that we got an iterator to the first spectrum, then one to the second one, which pushed the first out of memory so its iterator was no longer valid.
