    Problem Text
    This test may fail due to an invalid assumption of when file time
    fields must be updated. BR1170/130 clarifies this issue.

    Base WG resolution 1170/130 clarifies how msync() and stat() should be
    used to force data and meta-data updates. We suffer from the following
    three failures and on inspection of the test code for each case it
    appears that the boundary end time used in the test is being set
    before the stat() is called to update meta-data. Moving the stat() to
    before the setting of the end time for these three tests results in
    passes.
    Test Output
    TEST PURPOSE #34
    The st_atime field of a file mapped by a call to void
    *mmap(void *addr, size_t len, int prot, int flags, int
    fildes, off_t off) shall be marked for update on the
    first read or write reference to a mapped region.
    PREP: Obtain the system page size by call to
    sysconf(_SC_PAGESIZE)
    PREP: Establish signal handlers for SIGSEGV and SIGBUS
    PREP: Obtain start time
    PREP: Open a file and initialize it
    PREP: Allocate memory for buffer
    PREP: Now set proper permissions and re-open file
    PREP: Map a file
    PREP: Make write references on the file
    PREP: Obtain end time
    TEST: st_atime field is marked for update

    TEST PURPOSE #35
    The st_ctime field of a file mapped by a
    call to void *mmap(void *addr, size_t len, int prot,
    int flags, int fildes, off_t off) with MAP_SHARED set
    in flags and PROT_WRITE set in prot shall be marked
    for update between a write reference to a mapped
    region and the next call to msync() with MS_ASYNC or
    MS_SYNC.

    TEST PURPOSE #36
    The st_mtime field of a file mapped by a call to void
    *mmap(void *addr, size_t len, int prot, int flags, int
    fildes, off_t off) with MAP_SHARED set in flags and
    PROT_WRITE set in prot shall be marked for update
