Summary: s2j proxy calls happen in wrong DynamicEnvironment

Initial Comment:
I think it's reasonable to expect calls to an s2j proxy from Java to take place in the DynamicEnvironment of any surrounding Scheme interpreter.

This is not so, as the attached program demonstrates.

What is actually happening is that on creation of the proxy it makes a copy of the current DynamicEnvironment. All calls to the proxy then use that DynamicEnvironment.

Not only is this wrong, it is also dangerous: if calls to the proxy happen in multiple threads then we have multiple threads accessing the same DynamicEnvironment, which is bad since DynamicEnvironments are not supposed to be shared between threads and are not thread-safe.
