Library /sys$common/syshlp/sysmanhelp.hlb CLASS_SCHEDULE, MODIFY, Qualifiers, /WINDFALL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies that all processes in the scheduling class are eligible
    for windfall.

    The syntax for this qualifier is as follows:

       [/WINDFALL])

    By enabling windfall, you allow processes in the scheduling class
    to receive a "windfall," that is, a small percentage of CPU time,
    when the class's allotted CPU time has been depleted and a CPU is
    idle. Rather than let the CPU remain idle, you might decide that
    it is better to let these processes execute, even if it means
    giving them more than their alloted time.

    The default value is for windfall to be disabled.
