    Problem Text
    This test may fail on IUTs that only allow getpgid access to
    processes in the same session as the calling process.

    This test fails because it uses setpgrp() to set the process
    group ID and make the child a session leader. Therefore, the
    child is not in the same session as the calling process (the
    parent).

    The parent then tries to do a getpgid() using the child's pid.

    According to the getpgid spec getpid may fail with EPERM if

    The process whose process ID is equal to pid is not in the same
    session as the calling process, and the implementation does not
    allow access to the process group ID of that process from the
    calling process.


    Since we implement the call this way, getpgid fails and EPERM is
    set in the errno.
    Test Output
    TEST CASE: getpgid

    TEST PURPOSE #1
    A successful call to pid_t getpgid(pid_t
    pid) when pid is not 0 shall return the process group
    ID of the process whose process ID is equal to pid.
    PREP: Fork a child process
    PREP: Child: change group ID to its process ID
    TEST: Parent: getpgid() returns the process group
    ID of the child process
    ERROR: getpgid failed, errno = 1(EPERM - Not owner)
    1 UNRESOLVED
