Great! You have the "bible" on low-level implementation issues!
Of course, if you're at all like me, it will take several (uh... "many"!)
readings to absorb even a fraction of what's there.

One word of warning: Even Quiennec's book doesn't cover *all* of
the low-level issues you will run into when actually doing a full
implementation for the first time. So don't get discouraged when
you run into to one or two such issues... [Instead, go look at other
implementations -- SCM, Guile, Elk, SIOD, MzScheme, etc. -- and see
how *they* dealt with it. May not solve your problem, but should give
some hints.]

The "SCM" distribution <URL:http://www-swiss.ai.mit.edu/~jaffer/SCM.html>
contains the file "r4rstest.scm" -- also available separately from
<URL:http://swissnet.ai.mit.edu/ftpdir/scm/r4rstest.scm> --  which
tests many (though not all) of the features of an R4RS Scheme.
