Hm, might be that the rest of the 70% are spent in the kernel (doing IO
probably).  Do you do a lot IO?  Or do you start another process (or
multiple processes) from your Ruby script?  Did you have an eye on your
disk LED?  I'm not too familiar with top but I think I remember that it
sometimes spits out odd values - might be another explanation.

Guilty!!! :-)
