1 We have so far failed to find a good way to determine the stack base.
2 It is highly recommended that GC_stackbottom be set explicitly on program
3 startup.  The supplied value sometimes causes failure under AIX 4.1, though
4 it appears to work under 3.X.  HEURISTIC2 seems to work under 4.1, but
5 involves a substantial performance penalty, and will fail if there is
6 no limit on stack size.
