Disable completely two sets of Twisted tests so the suite runs.

The problem is that these tests are not just failing, they hang (even
ignoring Ctrl-C), so they prevent the suite from running at all.  But I
don't know how to fix them, so I disabled them; this way others can at least
run the test suite, and hopefully Brian can pitch in with a fix.
