  SVN rev 189545 on 2009-03-08 22:19:28Z by rwatson
  
  By default, don't compile in counters of calls to various time
  query functions in the kernel, as these effectively serialize
  parallel calls to the gettimeofday(2) system call, as well as
  other kernel services that use timestamps.
  
  Use the NetBSD version of the fix (kern_tc.c:1.32 by ad@) as
  they have picked up our timecounter code and also ran into the
  same problem.
