Description:
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,
and forced to change their patched state.
