You can drop the overhead even further by shutting down services that you don't need to run. Several of the commonly-started Linux processes will wait for a period of time, check for something, and go back to sleep. I briefly experimented with back-porting the timer patch to 2.2.16 (NOT for the faint of heart, and never entirely successful), and during one test run I shut things down one by one until I just had the kernel, inetd, and init running. With #CP TRACE INSTRUCTION (note no RUN!), it sat idle for several hours and never executed a single instruction. Ross Patterson Computer Associates
