      I occasionally see this failure:

      6: lsm, row-store                                                          
t, file:wt-000001.lsm, session.verify: RUNDIR/wt-000001.lsm: No such file or directory
t: session.verify: table:wt: post-salvage verify: No such file or directory

      and:

      t: salvage: dump comparison failed: Unknown error: 256

      which is from this code:

      /*
 * If no records are deleted, we can salvage the file and test
 * the result.  (The problem with deleting records is salvage
 * restores deleted records if a page splits leaving a deleted
 * record on one side of the split.)
 *
 * Salvage, verify the salvaged files, then dump (comparing
 * against the Berkeley DB data set again, if possible).
 */
if (g.c_delete_pct == 0) {
        wts_open(g.home, 1, &g.wts_conn);
        wts_salvage();
        wts_verify("post-salvage verify");
        wts_close();
                
        wts_dump("salvage", SINGLETHREADED);
}

      Michael's change in 07691a5 turns off the salvage step, but then the subsequent verify and dump calls are failing.
