Summary: script which sets random.seed still returns random value

Initial Comment:
Hi,

The following text is in the README in the attached
tarball. Note also that I'd be happy to try to narrow
down the bug further, if indeed there is one. I just
wanted to confirm first that there indeed was a bug.

This is with python 2.3 and numarray 1.0 on Debian sarge.
ii  python-numarray            1.0-2                  
   An array processing package modelled after
Python-Numeric
ii  python                     2.3.4-1                
   An interactive high-level object-oriented language
(default version)

(By the way, I'd really, really prefer to submit
reports via email, like the Debian bug tracking
system). It is also not very convenient to follow up to
replies.
                                                      
                      Faheem

*************************************************************
Run the included script (requires python 2.3)

python bug.py

Even though the seed is set before gendata is called,
every time the script is run, a different matrix is
printed. It seems to me that this should not happen. My
interest in this case is ensuring
reproducibility for debugging purposes.

I am not an expert on random numbers, so I may be
missing some subtle point. If so, I'm appreciate it if
my error was explained to me.

Thanks.                                               
Faheem Mitha.
