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.
