Run the test suite four times per package, once with each interpreter?
Well, of course it gives better coverage... But some test suites are
quite long to run. And if we reach a stage where the different
interpreters are compatible enough, it might be pointless.
Also, it bloats our build-dependencies. If I have to install
traditional Ruby, Java (to get jruby) and Mono (to get IronRuby), and
whatever it takes to run Rubinius... Well, setups will be huge.

Do you think Ruby has reached a stability point where it can be
handled through alternatives? i.e. where a user can change
/usr/bin/ruby to point from ruby to jruby and expect random programs
not to break?
