Well, if this modal dialog can be solved elsewhere, we might not need a
canDelete event if this ugly synchronization in KJavaAppletServer can be
implemented differently:
    while (!frame->ready && --count > 0) {
        usleep(50000);
        qApp->processEvents(100);
    }
Solution that I can think of is
- Running kjs in a subprocess that can be killed
- Return from evaluate with completion type UNFINISHED and continues
  running after data is arrived (or timed out)
Both not very feasible (certainly for 3.1)

Other suggestions?
