For a one-thread-per-player-system, wouldn't you have to make sure that
global variables aren't being accessed at the same time by two or more
different threads? That's what I was told, anyhow. So you'd need a flagging
variable on each global variable (or even on playing structures, seeing as
they can be accessed by different threads) ... kind of like a INUSE/FREE
thing. This would be mighty troublesome, wouldn't you agree?
