Throttling a process

Hi Vlad,

you could use instrument.erl I have never used it myself, so I am 
unaware over pitfalls/performance, but it appears to do the monitoring 
job. And if you want to get nasty, you have the bifs suspend and resume 
to start and stop your processes. If you use them, just make sure I do 
not get sent to Gothenburg to review your code ;-)

What I thought I could do is check erlang:statistics() and also follow a few well-chosen processes with erlang:process_info(). This information will then be used to set longer sleep intervals for my process, or to simply make it wait until load goes down.
