This seems to work perfectly, thanks for the idea.

Would there be an advantage using this option? If I understand
correctly, this would be very Boehm-GC centric; on the other hand, is
there a high probability that any non-Boehm C grade will get widely
used? For Java/C# and Erlang, they have their own implementations of
bigintegers.
