Scry (though lightly populated) rarely gets above 5% CPU. I would suspect
you have a busy-wait somewhere..or that you have an enormous amount of events
happening close together. Scry isn't threaded (uses a while loop, waits for
max .25 secs on IO before looping again to do AI and other timer based
activities.)
Did you try running some kind of performance monitoring tool (gproff?)
to see where the program spends all of it's time?
