  39 ** File:        lazyinit.c
  40 ** Description: Testing lazy initialization
  41 **
  42 **      Since you only get to initialize once, you have to rerun the test
  43 **      for each test case. The test cases are numbered. If you want to
  44 **      add more tests, take the next number and add it to the switch
  45 **      statement.
  46 **
  47 **      This test is problematic on systems that don't support the notion
  48 **      of console output. The workarounds to emulate that feature include
  49 **      initializations themselves, which defeats the purpose here.
