Yeah, mine is 022 as well.  However, if running:

     python -c "open('test.txt', 'w')"

results in a file with a umask of 644.  Which is the same thing I get if 
I run `touch test.txt` from the command line.  As I said, I don't really 
care that much if my messages are executable.  However, it is strange 
and something I've not seen before, either in my Python scripts or in 
general Unix usage.  Also, I thought a umask of 022 results in files 
with 644 (666 - 022 = 644).

So I guess my question has another part: Are you guys seeing 755 umasks on 
the messages?
