But very annoyingly the Go rselect, which can be read
as "run select" but I guess it could also be read as
"randomized select", requires shuffling the cases, even
for each invocation I guess.

And shuffling requires access to a random generator,
which might need some additional locking probably.
So after all I have the impression that the Go rselect
is not extremly simple.

Also I am not sure about the application scenarios,
those I have seen so far could be also solve with single
queue or even single priority queue. Just force your M:1
producer consumers to write into the same queue.

What could be an application scenario though, could
be something along 1:M producer consumer arbitration.

Still experimenting.

Bye
