Cool!  Is there any kind of in depth discussion of the garbage collector, things like ___STILL, etc.?  I remember a few mentions in the official docs, but not enough to wrap my head around.

Use this instead:

long length = 100;
___SCMOBJ init = ___FAL;
___SCMOBJ v = ___EXT(___make_vector)(length, init, ___STILL);

An alternative is to create the vector in Scheme, and pass it to C to be filled in using mutation.
