   7 ** File:        lazyinit.c
   8 ** Description: Testing lazy initialization
   9 **
  10 **      Since you only get to initialize once, you have to rerun the test
  11 **      for each test case. The test cases are numbered. If you want to
  12 **      add more tests, take the next number and add it to the switch
  13 **      statement.
  14 **
  15 **      This test is problematic on systems that don't support the notion
  16 **      of console output. The workarounds to emulate that feature include
  17 **      initializations themselves, which defeats the purpose here.
