Comment(by adept):
Ok. Following the discussion on IRC I've clarified the behavior of
{{{awaitSignal Nothing}}} and exported the value of the timer signal from
RTS. I hope that I did this properly - this is my "first export", so
please check carefully :)
I verified and
{{{
blockSignals reservedSignals
awaitSignal Nothing
}}}
behaves as expected and as advertised with -threaded and without.
