probably someone else might chime in with better explanation and/or
suggestion how to improve this.

It looks like a version of the patch with 2 tables is a bit slower

PS: (Nov 8, 2004) TCC version 0.9.22 is out (Changelog). Linux kernel
compilation is 30% faster (10 seconds on a 2.4 GHz Pentium 4).
