- A writable attribute that allows administrator to affect the
- course of an existing transition. Writing 1 sends a fake
- signal to all remaining blocking tasks. The fake signal
- means that no proper signal is delivered (there is no data in
- signal pending structures). Tasks are interrupted or woken up,
