  To help, it wasn't happening with a dll built from cvs on the 17th, but when
I updated and built from CVS this morning I suddenly started getting millions
of expect.exe windows spawning when I fired off the gcc testsuite!

[ Because I've got work to get on with at the moment I rolled it back, but
I'll spend some time trying to understand it later. ]
