     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.
