Need function to test if EFFECTIVE UID has read-access to a file.

Me again, haha

Okay, I've solved my problem. Rearranged my program logic and
eliminated the check  that was to verify if the dir are accessable or
not, because if yes I would have called os.listdir() a few lines down
in the code anyway. So I sort of did what Skip suggested and just
listdir'd catching any OSError exceptions that get thrown if the dir
is not accessible for some reason. =)
