      Description

      @michaelcahill, the test suite is currently failing in the develop branch on pixiebob.

      Here's the stack:

      It looks like one of the new asserts is firing?

      The program being debugged stopped while in a function called from GDB.
      When the function (__wt_txn_visible_all) is done executing, GDB will silently
      stop (instead of continuing to evaluate the expression containing
      the function call).
      (gdb) n
      133		oldest_id = txn_global->oldest_id;

      $4 = {current = 4, oldest_id = 4, scan_count = 0, states = 0x805c12c00}
      (gdb) n
