The //TODO comment before the no_selinux tag in transaction_too_large_for_cache.js is causing tag parsing to fail in the selinux test executor "core.js", which causes it to run the test regardless of the failure.

We need to 1. fix the comment in the jstest to use # instead of //, and 2. handle tag parsing errors in "core.js" so that such failures would cause early termination of the entire test.
