DrScheme won't take advantage of multiple processors to run multiple
Scheme threads.

DrScheme could take advantage of multiple processors in principle ---
not necessarily by mapping Scheme threads to OS threads, but certainly
using Scheme threads as clue for how work can be parallelized. Our
current run-time system, however, is not easily adapted to take
advantage of OS-level threads.
