-// I originally wrote this code to use CLOCK_PROCESS_CPUTIME_ID.  In Linux
-// this is a highly accurate realtime clock.  It turns out, though, that this
-// is a Linux bug.  This is supposed to be (posix says it is) a highly 
-// accurate cumulative running time of the process.  In Linux it is (or at
-// least was -- a bug is filed) a  highly accurate wall-clock time since the
-// process was created.  Posix defines the wall clock you must use as the
-// CLOCK_REALTIME clock.  As you can see in the constructor, the resolution
-// of the CLOCK_REALTIME clock is a jiffy.  This is not fine-grained enough
-// for us.  So, I'm using the gettimeofday clock even though it is an
-// expensive call.
-//
-// I could write some inline assembler here to get to the timestamp counter
-// (RDTSC instruction).  It's not as trivial as it sounds to get right.  
-// Google for "rdtsc cpuid" to see why.  I'm leaving this for another day.
-//
-// N.B. This returns the value of the realtime clock.  This does not return
-// the current normalized realtime that we are attempting to make equal to
-// the simulation clock.  To get that number, use GetNormalizedRealtime ().
