    sys/i386/conf        NOTES 
  Log:
  My recent measurement shows that CPU_DISABLE_CMPXCHG is no longer necessary
  with VmWare 4.x. At least with VmWare version 4.5.2, i386 version of
  atomic_cmpset_int() is about 30 times slower than non-i386 version. It
  makes this delta a good 5.3 MFC candidate, since otherwise it will
  mislead users who run FreeBSD under modern VmWare otherwise.
