access is not a problem, creation can be, it's not really atomic. It's 
something is was never seriously thought about.

What can be done in some cases is be sure that all .py files are 
precompiled to *$py.class.
It is something the installer ought to do, but currently doesn't. The 
CPython AFAIK OTOH does that. Relevant:

http://www.python.org/doc/2.1/lib/module-compileall.html

it works in Jython too.

This kind of issues are present in CPython too, for some finer control 
there as an open
PEP, it's still not implemented even in CPython. For info it can be found here:

http://www.python.org/peps/pep-0304.html
