Something weird is happening: I'm seeing drracket-compiled files where
I do _not_ expect to see them:


---------------
slab:collects dyoo$ find . -name '*.zo' -print
./compatibility/compiled/drracket/errortrace/mlist_rkt.zo
./compatibility/compiled/drracket/errortrace/package_rkt.zo
./compatibility/compiled/drracket/mlist_rkt.zo
./compatibility/compiled/drracket/package_rkt.zo
./compiler/compiled/drracket/cm-accomplice_rkt.zo
./compiler/compiled/drracket/errortrace/cm-accomplice_rkt.zo
./compiler/private/compiled/drracket/errortrace/mach-o_rkt.zo
./compiler/private/compiled/drracket/errortrace/winutf16_rkt.zo
./compiler/private/compiled/drracket/mach-o_rkt.zo
./compiler/private/compiled/drracket/winutf16_rkt.zo
...

Throughout the whole collects tree, I'm seeing that DrRacket has
compiled many (if not all) the standard collections with DrRacket.
That can't surely be right, right?
