Ok, yeah - that's something that people are running into a lot,
passing proxies into prims.  At some point it would probably be useful
to go through the image and find all prims that take arguments that
are non-immediate in GOODS, and maybe construct a set of wrappers for
them.  There seem to be about 450 prims in the stock image that take
args at all, but I suspect that many of those expect SmallIntegers or
other values that wouldn't be proxied anyway, or have useable
Smalltalk fallback code, in which case we can safely ignore them.
