Someone submitted a bug stating that calling "python setup.py clean" 
leaves an unpredictable set of .pyc files lying around.  This could be 
reproduced, and therefore we clean them now.  I have not yet seen a 
test case that lets .pyo files lying around.

For example, I looked at the package python-weblib-1.3.3.  Its setup.cfg 
contains

[install]
compile = 1
optimize = 1

I don't know if that's the same as your case, but anyway.  Running clean 
leaves a file

./pyweblib/__init__.pyc

but there is no file ./pyweblib/__init__.pyo or anything like that.

So before we go around deleting .pyo files, we at least need to see 
some .pyo files that need deleting in the first place.
