[racket] confusing behaviour of managed-compile-zo

Aha, that (in addition to what Matthew already answered) could be it, I
always have automatic compilation enabled, even while compiling. I'll look
into it.
Thanks, Jos

There was a related problem that Sam noticed a while back about how the same
set of parameters (if not the same uses) leaked out into his program and the
best I came up with was the advice to disable the automatic compilation in
DrRacket (in the language dialog's "show details" section).

I think the issue is that DrRacket sets `use-compiled-file-paths' to
include "compiled/drracket/errortrace", and the installation doesn't
includes compiled files there, so CM tries to add them.

In other words, there's a collision between your use of CM via
`managed-compiled-zo' and a use already in place for the load handler.
You can work around the problem by setting `use-compiled-path-paths'
back to just `(list "compiled")'.

Meanwhile, I'm not sure which part of the system to blame. I think the
pile of parameters and callbacks isn't right, since DrRacket interferes
with your program, but I don't immediately see how to fix it.
