No bait intended, honestly! Sorry it was taken like that but, to be
honest, I can see why now I read it back ;-).
My comment on Myghty was meant as nothing more than a comment on how
hard it is to know **for sure** in **any library** that there are no
thread-related problems left.

What I really meant is that threaded programs are harder to debug and
harder to "prove" correct.
Like I said, concurrency can be hard. Working in an (purely) event-based
system means that you at least know a bit of code you're writing of
debugging is not going to get pre-empted by another thread in the same
process.
