I thought it was in the docs? Unless it was removed.. I remember 
specificly reading the Allegro can only handle 16 timers total and that 
parts of Allegro itself use those timers. In Windows, the mixer callback 
 (which handles the sweep effects) is in a timer, but in Linux it's in 
the bg manager thread.
