Thank you for your responses Taylan and Maxime!
My initial reaction to the concern about multithreaded code is similar
to Taylan. I'm not sure if Guile has multithreading concepts built into
the compiler. If so, one can only check the length again after a mutex.
Appreciate the malloc, realloc, and free FFI solution. Ideally I
wouldn't have to do that, but it does work. I have to manually free it
though.
