[Numpy-discussion] random number generator--problems?

Hello:
I just ran across this article saying that the random number generator in Linux is broken.  

http://www-cdf.fnal.gov/publications/cdf6850_badrand.pdf

The article starts:
<<The main purpose of this note is to exhibit a defect in the Linux C and C++ standard library pseudo-random number generator rand and the Linux/UNIX
system-library generator random. Since Linux rand and Linux/UNIX random
use identical algorithms, we will use “random” to refer to both. The defect
is uncovered when random fails a simple empirical test.>>

As I understand it, Numpy uses a different random number generator (Mersenne Twister), but I just wanted to verify that any problems with the Linux random number generators do not apply to Numpy.  Can someone please verify this?

Thanks
John
