[cod] Random strangeness on serve

COD2 _does_ use the rdtsc opcode on Windows, so if you have an SMP box 
with unsync'd processors, you can see strange behaviour.

All of those problems you listed were visible in the Linux server before 
I swapped out rdtsc for the gettimeofday syscall.

I bet all of those problems you see have a matching log entry about 
scripts being killed for potential infinite looping, too.
