So at least the BSD I work with (OpenBSD-current) has 32. And it has had
the value 32 at least since the OpenBSD CVS repository was created.
If the Linux kernel groks a recursion depth of 32, that would
probably be the way to go for 2.2, I think. But the idea of using
the Tarjan algorithm for loop detection is pleasing!
Regards, Felix.
PS: Yes, in computer things 32 *is* a rounder number than 20 :-)
