testbios and the system timer

[ron minnich]

OK, I finally read this in detail and I'm sorry for my noise on this 
subject. 

I think it would be useful to keep an 'emulated instruction count' in the 
emulator, and have a virtual timer that increments very X (pick a number) 
instructions. X can be constant across different architectures as we are 
somewhat divorced from time (it's an emulator). 

The emulated timer would increment every emulated instruction count ticks. 

Would this do it?
