This is a great addition for the Jacl world. However I found that it 
doesn't provide any improvement when executing a large number of small 
procedures. I suspect speed improvements only occur when the overhead of 
setting up the environment for the compiled version at runtime is small 
compared to the execution time of the compiled code.

For example 36,000 executions with various arguments of a simple 
procedure with about 50 lines of code gave total runtimes of

raw jacl = 138 seconds
compiled jacl = 144 seconds
coded in java = 5 seconds

This is embedded in a real application so a lot of execution time was 
consumed elsewhere in the Java code.

I would be interested in hearing if anyone else has done any comparisons 
for larger jacl code procedures.
