[kw-pm] Seeding srand

[Max]

Changing the seed won't really affect the output distribution.  That 
would seem to be a limitation in rand().

The funny thing is when I run on one server the results skew "greatly" towards the extremes (i.e. 0 or 3 - slighly more than 75% of the random numbers generated are 0 or 3). On another server the number 3 has never gotten hit after over 200 trial runs. Both servers are Windows machines.
