Throttling theory:
This routine is called periodically with an up-to-date emulated time.
The idea is to synchronize real time with emulated time. We do this
by "throttling", or waiting for real time to catch up with emulated
time.
In an ideal world, it will take less real time to emulate and render
each frame than the emulated time, so we need to slow things down to
get both times in sync.
There are many complications to this model:
* some games run too slow, so each frame we get further and
further behind real time; our only choice here is to not
throttle
* some games have very uneven frame rates; one frame will take
a long time to emulate, and the next frame may be very fast
* we run on top of multitasking OSes; sometimes execution time
is taken away from us, and this means we may not get enough
time to emulate one frame
* we may be paused, and emulated time may not be marching
forward
* emulated time could jump due to resetting the machine or
restoring from a saved state

We do this\r\n by \"throttling\", or waiting for real time to catch up with emulated\r\n time.\r\n\r\n In an ideal world, it will take less real time to emulate and render\r\n each frame than the emulated time, so we need to slow things down to\r\n get both times in sync.\r\n\r\n There are many complications to this model:\r\n\r\n * some games run too slow, so each frame we get further and\r\n further behind real time; our only choice here is to not\r\n throttle\r\n\r\n * some games have very uneven frame rates; one frame will take\r\n a long time to emulate, and the next frame may be very fast\r\n\r\n * we run on top of multitasking OSes; sometimes execution time\r\n is taken away from us, and this means we may not get enough\r\n time to emulate one frame\r\n\r\n * we may be paused, and emulated time may not be marching\r\n forward\r\n\r\n * emulated time could jump due to resetting the machine or\r\n restoring from a saved state\r\n\r\n*/",
