+;;;; PCOUNTERs
+;;;;
+;;;; a PCOUNTER is used to represent an unsigned integer quantity which
+;;;; can grow bigger than a fixnum, but typically does so, if at all,
+;;;; in many small steps, where we don't want to cons on every step.
+;;;; Such quantities typically arise in profiling, e.g. 
+;;;; total system consing, time spent in a profiled function, and
+;;;; bytes consed in a profiled function are all examples of such
+;;;; quantities. The name is an abbreviation for "Profiling COUNTER".
