It's taking a long time to minimize this, let me now if minimizing further is useful.

Obvious things:

1)  When jitting we spend a huge amount of time in MonitorLoopEdge and
    Array.splice
2)  We're executing the code wrong.  In particular, without jit we only run the
    splice() calls 7 times, while with jit we run it at least 15000-some (after
    that I killed the process).

hope this helps to minimize the test case.

Everything seems to be working using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b1pre) Gecko/20081007 Minefield/3.1b1pre 20081007033730

- No script running too long error
- Examples seem to be working as expected
