Re: [asio-users] immediately stopio_service fromexecuting furtherwork (but not with strands??)

Batching is an optimization.  Optimizations should not violate
correctness (by default).

If you want to add batching, please make it configurable and set the
default batch size to be 1.

Batching is needed. It's a classical multithread tradeoff. But it would
be rightly to give users of strand an opportunity to configure max size
of such batching (optional second parameter of strand's constructor).
