I don't think that would work.. both we and they would be allocating LDTs.. which one would be loaded? if tey just left the LDT alone they could use ours as long as we left room for them to do so.. they said they only need a few entries at the head.. Alternatively thay can compile using __thread when we support it.. > > -- > Dan > >
