    Linked Problem Reports Problem, Report, 1396
    Problem Summary Sporadic '/tset/rt.os/ioprim/close/T.close 3 Failed', 'Child 2: Page
    still accessible after unmap' results occur when the memory is re-used
    by the same process.
    Problem Text The test assertion appears to assume that the memory cannot be re-used
    by the same process prior to it attempting the page access; when that
    occurs, then the anticipated memory access failure does not.

    Our testing indicates that the page in question gets remapped by the
    same process between 4% (S10) and 7% (S11) of the time; this test fails
    only on those occassions.

    Note that PR 1396 appears to have addressed this in the munmap test, we
    are seeing these sporadic failures during close testing.
    Test Output **********************************************************************************************************************************************
    /tset/rt.os/ioprim/close/T.close 3 Failed

    Test Description:
    If _POSIX_MAPPED_FILES or _POSIX_SHARED_MEMORY_OBJECTS is defined:
    When fildes refers to a memory object that remains referenced at the
    last close() (i.e. is mapped by a process), the entire contents of
    the memory object shall persist until the memory object becomes
    unreferenced.

    Test Information:
    Child 2: Page still accessible after unmap
    Child 2: Page still accessible after unmap
