Remove memory leaks in isolationtester. specscanner.l leaked a kilobyte of memory per token of the spec file. Apparently somebody thought that the introductory code block would be executed once; but it's once per yylex() call.
A couple of functions in isolationtester.c leaked small amounts of memory due to not bothering to free one-time allocations. Might as well improve these so that valgrind gives this program a clean bill of health. Also get rid of an ugly static variable. Coverity complained about one of the one-time leaks, which led me to try valgrind'ing isolationtester, which led to discovery of the larger leak.
