neat!  two comments:

- /proc/meminfo is linux specific and less general.  perhaps you could write 
something with "free" or some other generic utility instead?
- your suggestion isn't mutually exclusive from the previous one i made.  it 
could be made optional to specify a timeout value, and if not specified, use 
the heuristic you provide, which would be the default.

but in any event, i think it's a great idea.  monty: you think this is 
something mysql.com would be interested in?
