By the very slow process of elimination until I had the minimal amount
of code which caused the problem.  Then running the debug version of the
collector with backtraces and realising that gc wasn't causing a
problem.  I do remember at an earlier stage, actually looking at the
code for the pthread library implementation, but somehow I managed to
convince my self that I only did a fixed number of mallocs in the code,
so it couldn't be a problem.
