First, don't write to the Transcript directly from a non-UI task, as this 
isn't guaranteed to work correctly. If you *must* write to the transcript 
from a non-UI task, then: 

* only do it using #addDeferredUIMessage: like this:

 WorldState addDeferredUIMessage: [ Transcript nextPutAll: someString; 
nextPutAll: 'something else'; cr ].

* use nextPutAll: instead of show:

* if you must force the output to be visible (which takes more CPU time 
because the screen must be updated), then call endEntry .

Second, try to break up the writing by waiting on a Delay, and/or reduce the 
priority of the reading thread to equal or less than the priority of the 
Seaside threads.
