In fact, Debian (and I'm sure other OSes with package managers) precompiles
source files at installation time.  We have a couple of bugs languishing to
provide -OO optimization levels as an option when doing this precompilation.

I haven't pushed this forward because I got side-tracked by the overloading of
.pyo files for -O and -OO optimization levels.

I agree that the flags, mechanisms, and semantics should be worked out first,
but I also think that PEP 3147 tagging will provide a nice ui for the file
system representation of the optimization levels.
