We could make the "void *cookie" returned by softint_establish(9) an index (internally) instead (w/o changing ABI or API), so the value would stay valid on reallocations of the array. The realllocation could be handled lazy per cpu (that is: note the new target size globaly, have the local cpu handle the reallocation at next time a softint is established/disesatablished/scheduled). But maybe I'm overlooking something. Martin
