I've now checked in ack.pir and ack.py into examples/benchmarks. And
I've timed Ack(3, 9) with an optimized Parrot build:

Parrot -j 15.3
Parrot -C 13.8
With recent parrot (r10436) and mostly due to this patch ...
$ diff ack0.pir ack.pir

... i.e. using the same call signature for all ack() calls, I'm now at:
Parrot -C 9.0 secs
Getting a similar optimization into Parrot itself is a bit beyond
current goals (albeit simple), but the numbers are indicating that the
new calling conventions are a lot faster than old.
