All this is very interesting, but you neglect to mention
anything like what hardware you're running this on, which makes it
kind of hard to compare your numbers to anything.
Also, I'm curious how Python deals with issues of untrusted code.
I don't recall reading anything about this.
As for VHLL features, I don't think this was one of the goals of
Java, but I'll leave that question to the Sun people. There are
certainly some features that seem to be lacking, but I suspect
that this is because these features are difficult to implement
in a secure way.
I can vouch that Java _is_ extensible, as we did some simple
crypto wrappers over the weekend. The process could be a little
better documented, and I'm in the process of trying to reproduce
what looks like a bug we found, but it's a fairly solid process.
My only real concern stems from the fact that extensions leverage shared
libraries, which are implemented in N different ways on any given
N platforms.
