[Swift-devel] scalability updates

[Ben Clifford]

Here's a different looking one.

Trying to run 066-many with 30000 iterations, in one run I got the below 
error within a couple of seconds; and in a subsequent run it happened 
after 20s or so.

http://www.ci.uchicago.edu/~benc/tmp/066-many-20090311-0336-toznl2a0.log

Full exception is in the log but in summary:

> No named arguments on current frame
>        at org.globus.cog.karajan.arguments.Arg.getNamed(Arg.java:52)
>        at org.globus.cog.karajan.arguments.Arg.getValue0(Arg.java:66)

I got what looks like its a similar error when I tried running with 3000 
iterations, in
