I would have guessed that it might sometimes make the problem slightly worse, since it may increase the collectors idea of how much stack space it's scanning, especially since gctest is deeply recursive in one or two places.  If you want to check in the patch, fine.  But I think that if we want to really improve matters we should at least take the number of threads into consideration.  We clearly have another problem, which I don't yet understand.

I think completely the same (I'll check it in later (after fixing the major problem) - just to treat the multi-threaded case running in the single-threaded mode the same as a single-threaded case.

Ok. (BTW, MinGW fits too (except for, may be, the simplicity of debugging an app).)
