/**

 * have finished sending primitives down the pipeline, and to allocate a URB

 * is true.
 *
 * This function modifies c->reg.header: in DWORD 1, it stores num_prim (which
 * is needed by the FF_SYNC message), and in DWORD 0, it stores the handle to
 * the allocated URB entry (which will be needed by the URB_WRITE meesage that
 * follows).
