//
// polclock.h - clock() and time() wrappers for clock stretching
//
// This is mostly for profiling, so that timed actions (ie attacks) don't
// overwhelm everything else.  Profiled runs seem to run at about 1/20th
// normal speed.  This way, you can run the system such that even though
// the RPMs are, say, 20, the profiling is similar to an RPM=400 system.
