    Problem Text
    This test fails on our implementation as it assumes that a read on a pipe
    cannot be satisified if the receiver is in a stopped state. It further
    assumes that upon returning from the signal catching function after receipt
    of SIGCONT, that read() returns -1 with errno set to EINTR. This was
    submitted to IEEE for interpretation (1003.1-1990 #64) with the resolution
    stating that it is conforming behavior for read() to return successfully.

    A similar argument can be made for write().
    Test Output
    ************************************************************************
    /tset/POSIX.os/procprim/sigconcept/T.sigconcept 35 Failed

    Test Description:
    If _POSIX_JOB_CONTROL is defined, when any of the functions fcntl(),
    open(), pause(), read(), sleep(), sigsuspend(), tcdrain(), wait(),
    waitpid(), and write() are stopped by the delivery of a signal whose
    action is to stop the process, the subsequent generation of a SIGCONT
    signal that is being caught by a signal catching function shall cause
    the process to continue after returning from the signal catching
    function with the function reporting that it has been interrupted by
    the SIGCONT signal.
    Posix Ref: Component Signal Concepts Assertion 3.3.1.4-48(C)
    Posix Ref: Component Signal Concepts Assertion 3.3.1.4-49(C:D)

    Test Information:
    function reported no interruption by stopping or SIGCONT signal
    read() returned 1 errno 10, should return -1 errno 4
    function reported no interruption by stopping or SIGCONT signal
    write() returned 1 errno 11, should return -1 errno 4
