You can now set the PLTDISABLEGC environment variable before startup to
disable GC.

I didn't add a way to disable/enable GC within Racket, because it
creates sandboxing issues. Unsafe code could use the FFI to call
scheme_enable_garbage_collection(int) (which I now realize I forgot to
document, so I'll fix that).
