I see a few possibilities. I think that this is a problem specific to
people who work regularly with SVN, so we can expect such people to
have extra sophistication:

  - (IMO, the second best option and one that is available now):
instead of saying "mzscheme file.ss", say "mzc file.ss && mzscheme

  -  (IMO the best option): mzscheme should get a commandline option
that amounts to doing the above for you automatically. So intead of
"mzscheme file.ss" yo'd say "mzscheme --compile-zo file.ss" or

  - disable automatic compilation in drscheme.

  - (the saddest option): by default, have automatic compilation in
drscheme turned off by default
