Subject: [PATCH 3/3] Use cache dir for classes too
Instead of attempting to write them next to source files.
Java 6 API does not allow for setting sane permissions (i.e. same as
those of a source file) and relying on defaults is a security hazard
which can lead to information disclosure, or, in case of a too relaxed
umask, arbitrary code execution.
Also, this will likely improve performance for non-privileged users
which can not write to their distribution's packaged jython tree.

Sensitive information might be being cached or umask can be too relaxed,
allowing writes.
