Re: [Jscheme-devel] Patch to allow multiple independent JScheme instances

[Toby A. <tob...@pe...>]

[I hope you don't mind me CCing this to the devel list.]

The basic idea is so that you can be running under one evaluator and
then create a new one and run some isolated Scheme code.  The tests I
added are examples of this.

This could also be achieved by changing the JS.enter and JS.exit methods
to save and restore the previous evaluator, but I prefer it to be
explicit.  The semantics of creating new threads are a bit easier to
understand with an explicit stack, in my opinion.
