[racket-dev] Recompiling on "wrong version for compiled code"

Hi all,

Is there some reason the compiler can't either (a) ignore or (b) replace
the outdated .zos when it comes across a situation like the following?

compiled/html-utils_rkt.zo::0: read (compiled): wrong version for
compiled code
compiled version:
expected version:

I just ran into this issue with a webservice I run: I had updated Racket
but forgotten to blow away the compiled .zos of the webservice, so when
I restarted the service, it repeatedly failed until I went and deleted
the .zos by hand.
