I have a question about the C interface. It appears necessary to decrement the reference count of ___STILL objects before returning them:
___SCMOBJ foo() { ___SCMOBJ result; ___EXT(___CHARSTRING_to_SCMOBJ) ("hello", &result, 0); ___release_scmobj (result); return result; }
Why is there not a race condition between decrementing the reference count (___release_scmobj) and returning the result? What if another thread wakes up the GC in the meantime?
