In addition to the suggestions up to now, you could think about  
gathering randomness from various different sources - for example  
using a seed which is a hash of the time, the process ID, machine  
name, /dev/random etc.

To address your problem of reproducibility, have the code print out  
(or otherwise report/save) the random seed that it is actually using,  
so you can re-run with that same seed if you wish.
