continuation barriers

[Linas Vepstas]

I just tried continuations for the first time in my environment, and
promptly hit a continuation barrier.  I think I understand why,
-- its how I'm mixing C and guile -- but don't see any solution.

I think what I want is a "continuation since the last time I
entered guile, and don't worry about C because there
aint none" .

i.e. I'd like something like this to work:

scm_c_eval_string(" ... (call/cc (lambda (k) (set! *myk* k))) ...");
... some_c_code(...);
scm_c_eval_string(" ... (*myk* 42) ...");

I think (I haven't yet tried) that the above can work if I wrap
the whole darn thing with scm_with_guile() .. but is there
some way of getting the above to run without a big wrap
of this kind?
