The method I have been using for getting something running in the
background is writing the code as a device driver that is in the
system heap and locked and the dNeedTime bit set. This seems much
safer than patching traps, and unlike VBL tasks (at least in THINK
C 4.0) you can have global variables floating around and call routines
that move memory. All the INIT does is call OpenDriver and exits.
