[plt-scheme] solving the halting problem

Hi all,

I'm interested in how the "break" key in drscheme is implemented - does it
kill the (PLT?) thread which the process is currently running in? Is this
the best/only way of manually stopping computation?

In the context of mzscheme and embedding - I assume the only way to do
this is from inside the interpreter? i.e. there is no magic asynchronous
version of scheme_eval_string which can be stopped.

cheers,

dave
