New Revision: 334550
URL: https://svnweb.freebsd.org/changeset/base/334550

Log:
  Revert r326083, it doesn't behave as expected.
  
  Even though there do appear to be more artificial frames, with 12, stack
  traces no longer list at all.  Revert until a better, more stable value can
  be determined.
