It looks like the CDP code base does random number generation in some non-ideal ways :
1) It uses the standard C library rand() function, which has notoriously bad implementations in the wild. Solution : Use a higher quality random generator such as Mersenne Twister.
2) It uses the system time in seconds to seed that rand() generator. Solution : Get the random seed from a higher resolution clock or an actual entropy source on the system.
I am not sure how easy these are to fix in a C codebase, but I could look into what is available...
edit : I was able to pop in a Mersenne Twister generator that is seeded from a higher resolution clock. Of course this needs further testing etc...
