    Specification Base Definitions Issue 6
    Problem Summary The helper function waste_time() does not run long enough
    Problem Text The problem with this assertion is that on faster machines, waste_time()
    is not running long enough for utime to be non-zero.

    The utime loop in waste_time:

    for (count = 0; count <= 1000*COUNT_UT; count++)
    dummy = dummy + count / (dummy + 1) * (dummy % 3);

    And COUNT_UT is defined as:

    #define COUNT_UT (1000 / SPEEDFACTOR) /* count for user time
    wasting */

    Setting SPEEDFACTOR to 1 is not sufficient to get the loop to go long
    enough.

    By increasing COUNT_UT by an order of magnitude (10000 / SPEEDFACTOR)
    the test passes.

    Increasing COUNT_ST is probably also a good idea to extend the lifetime
    of this assertion.
    Test Output ****************************************************************************************************************
    /tset/POSIX.os/procprim/fork/T.fork 5 Unresolved

    Test Description:
    The child process's values of tms_utime, tms_stime, tms_cutime, and
    tms_cstime are all set to zero.
    Posix Ref: Component FORK Assertion 3.1.1.2-10(A)

    Test Information:
    deletion reason: tms_utime and tms_stime are not
    both non-zero before fork()
    utime: 0; stime: 2
