A filesystem path based way to poll for ‘signals’. Cloning makes
another receiver that checks independently from the original (but
both receive the same ‘signals’).
A filesystem path based way to poll for ‘signals’. When receiving
a signal, it has to be confirmed explicitly, and the confirmation
is shared amongst all readers (usable for “work was done” on a
‘versioned’ input; the work confirmed refers to the version of the
signal that was read; the confirmation with the highest signal
value is stored). Note that multiple readers might start doing the
same work at the same time. Cloning shares the same receiver and
sender.
