As I understand it it's also important to consider how often the test will
fail.  Exception handling seems to be relatively cheap *unless* you actually
raise errors, at which point it becomes extremely expensive.

Of course you could also rename your #2:notfound() verb to #2:*, and then
calls to nonexistant verbs will automatically be handled by that.  ;-)
