Pardon my non-programmer's possibly completely misguided ramblingss, but...

For the longest time Dungeon Crawl relied on the system RNG for its RNG needs. 
The Windows system RNG poorly handled (handles?) long strings of consecutive 
RNG picks in such a way that gold generation was completely different for 
Windows builds than for Linux builds. The sole developer at the time didn't do 
Windows, so this came out really late, and natural it was a major balance issue!

The moral of the story - if there is any important process in Sangband funded 
on long strings of consecutive number picks, then this could be more important 
than it seems.
