RT rejected it (too big).  I gzipped it and attached it separately.  See 
also http://www2.zastoupil.org:8080/~paulz/gprof.out which is the same 
game I think.

Right now I'm looking most closely at the auto_arrange_workers call in 
update_city_tile_status().  This is called any time an enemy unit makes 
a worked tile unavailable.  This call seems to account for 2/3 of the 
aaw calls and 20% of the overall server runtime.  This call is 
fundamentally unnecessary, but fixing it isn't that easy.  However a 
simple greedy algorithm to move a SINGLE worker would be the best way to 
fix it (currently we place all workers from scratch).
