[gambit-list] JavaScriptScheme: too much recursion

JSS uses CPS conversion and trampolines, so the call graph is (should
be?) of a small constant depth. I don't know why you are getting a
"too much recursion error". The only thing I can think of is that the
JavaScript code itself is too heavily nested (syntactically) and the
JavaScript interpreter/compiler overflows the compile-time stack while
parsing/compiling the code. Does the problem occur for large files
only? Have you tried JSS on other browsers? I'm curious which ones
encounter the same problem. Do you have a test case I can try?
