Most programs are not multi-threaded.  Compiling using a multi-thread 
option almost always results in libraries being used that do thread 
synchronization.  If an application never creates multiple threads, 
but links in these MT libraries there is an unecessary amount of 
overhead.  All of this combines to make me conclude that threading 
should be single by default.
