      After a recent extension of max wait time in test_bug019.py by WT-4331, the test failed again on the PPC machine.

      There seems to be another place in the test program that are set to wait for 30 seconds:

       63     # Wait for a log file to be pre-allocated. Avoid timing problems, but
       64     # assert a file is created within 30 seconds.
       65     def prepfiles(self):
       66         for i in range(1,30):
       67                 f = fnmatch.filter(os.listdir('.'), "*Prep*")
       68                 if f:
       69                         return f
       70                 time.sleep(1.0)
       71         self.assertFalse(not f)
