the CASETABLE torture target now generates the complete unicode
equivalence table for a server. This was inspired by the chargen win32 code from monyo. This takes a *long* time to run against a Samba server due to the case insensitive comparisons in the filesystem. That makes it a N^2 operation, and N is 64k. It is linear on NT. (This used to be commit 441f9415b365787854fb0d3e04d1ea4938d7af73)
