    Test Identification base/execle 2
    Problem Summary TSD4U.00195 This test may fail on implementations where the child does not have enough time to set up the signal handler.
    Problem Text
    This is a problem of missing synchonisation between parent and child
    process. The parent process forks a child, that executes program 'check'.
    Program check initializes a signal routine for SIGINT.

    The parent sleeps 2 seconds and then sends the interrupt character.

    On our slow machines fork/exec and setup of the SIGINT handler sometimes
    takes longer than these 2 seconds. This results in 'Child
    terminated due to signal 2'.

    There should be a kind of synchonisation between parent and child processes.

    The same is true for

    fexecle 2
    fexeclp 2
    fexecv 2
    fexecve 2
    fexecvp 2

    Ref. to TSD4U.00191 (execl)
