You can use os.path.abspath(module.__file__) to get the absolute path of
a module. This works reliable unless you use os.chdir() in your code.

abspath() may not normalize symlinks (not sure about it) but you can
check for symlink with os.path.islink() (uses os.lstat) and resolve the
link with os.readlink().
