Re: Okay this is even odder

Here are some results for you. It is interesting to note that performance
under concurrency actually _degrades_ with the IBMJDK. Whether this is
due to thread safty issues in AServe, idiosyncracies in the IBMJDK,
or the finickiness of my tricked out dual Celeron is not clear to me.
Apache obviously yields benefits from the presence of two processors
and Kaffe's performance remains predictable even though unimpressive.

I cannot successfully get Toba to run with concurrent requests and it
even has problems with single threaded operation. It is, however,
relatively performant.
