Without trying to explain the whole design, this wouldn't be a good idea.
Polling in general is not something I want these tasks to be doing and any
attempt to introduce non-blocking I/O and/or polling amounts to a redesign.
If I'm going to redesign, then I'm going to redesign something different
that doesn't amount to just beating the existing design with a club until it
surrenders. :-)
