2131,concprog001(threaded2) occasional failures.,simonmar,simonmar,"This one has so far resisted my attempts to debug it.  The most common error is ""thread blocked indefinitely"": I don't know whether it's a bug in the RTS or allowed behaviour for this program, but it only seems to occur on a multiprocessor with `+RTS -N2`, and only in one out of 10 runs or so.
