@wpoely86 please review?

looks good but maybe also protect against __init__.pyc?

[boegel]

Having an __init__.pyc is irrelevant; the non-init *.py files are symlinked in a temporary directory, and then eb adds it's own __init__.py along with the symlinks. If the __init__.py files are symlinked too, things break.

So, good to go imho, thanks for the review @wpoely86!
