Ow, is that the only way? =( Because as I see it, open() is a
relatively costly function compared to something like os.access(), and
since I'll be calling the function thousands of times in a row it'd be
really cool if there was something similar to os.access(). But if
there isn't I guess that'll have to do ...
Thanks for helping!

Regards,

Markus
