My understanding is that COW filesystems have really bad fragmentation if you're changing portions of large files -- for example, with virtual machine disk images.

I'll assume that there are two players, and that you spin the cylinder at the beginning, but not after each turn. If this is the case, then at the start, the die is cast; the bullet is in one of the chambers, each with equal probability. It
