ACP_WORKSET sets the default size of a working set for an ACP.
    A specification of 0 permits the ACP to calculate the size. This
    value should be nonzero only on small systems where memory is
    tight. Too small a value causes excessive ACP page, while too
    large a value causes excessive physical memory to be consumed
    by the ACP. Note that this parameter has no effect on the per-
    process XQP.

    ACP_WORKSET is a DYNAMIC parameter.
