Yes, notably all the .rb files.

This is fine.

Actually it depends.  I hadn=E2=80=99t noticed, but since all the .rb source
files are there, uncompressed, that means that if a reference is
embedded in the source, it *will* be scanned correctly by the GC.

So maybe there=E2=80=99s no real problem, after all.
