 It's so easy to dump stack traces these days!

 I have a "backtrace" branch right now that an dump stack traces on
 assertion failures.  It works on glibc/ELF, and on OSX.  We should expand
 it to work on Windows too, and BSD if we can.

 Other fixes to make before it's ready:
   * It should be able to log a stack trace too.
     * It should log the stack trace on an assertion.
   * There should be an option to tell it not to log to the stack_dumps
 file, perhaps.
   * Perhaps the logfile should be pid-controlled?
   * It should support Windows.
   * It should handle deadly signals (SEGV, etc) as well.
   * It should indicate to the user somehow (if it can) that stuff might be
 saved to the stack_dumps file.
   * It should have tests.
