I believe that is a stack space issue. The release version of
wackamole requires and inordinately large stack size. While that might
be common in unithread applications, it isn't in multithreaded
applications. I think the CVS version has this problem fixed -- I'd
love to know if people still see the same problems with CVS HEAD.
