Fortran code could scream. Test times were reproducible to the nanosecond with no effort. Running on a modern box for a few microseconds at a time is a way to approximate that, provided you measure the minimum time with a high-resolution timer :-)

On Linux with a multi-CPU machine, you could probably boot up the system to use N-1 CPUs, and then start the Python process on CPU N. That should avoid the process being interrupted by other processes, though I guess there would still be some noise from memory bus and kernel lock contention.

(At work we're trying to move toward this approach for doing realtime audio: devote one CPU to the audio computation and use other CPUs for I/O, web servers, and whatnot.)
