A git bisect shows that this [https://github.com/mantidproject/mantid/commit/f94f814ce5e1d89785aece20fa280c2963b94b40 commit] has caused some systemtests, particular ARCSReduction, to start segfaulting part way through.

gdb shows that the problem is around the ParameterMap access but the segfault actually occurs in boost code.

My suspicion is that switching to boost::unordered_map has uncovered a subtle race condition that was already present.
