single_producer_sequencer sample code appears broken

[jeanga]

Hi,

I've been trying to implement the single_producer_sequencer pattern in my code and based my attempt on the sample code here:
https://github.com/lewissbaker/cppcoro#single_producer_sequencer

Unfortunately, apart from small errors in the code (producer() does not take a thread_pool but an io_service), and missing main() and processMessage(), when I get to some compilable code, it hangs and never exits...

Here is the main() I used:

int main()
{
  cppcoro::static_thread_pool tp{8};
  cppcoro::io_service ioService;

  cppcoro::sync_wait(example(ioService, tp));

  return 0;
}

My environment is Win10, VSVC 16.10.

Anyways, thank you for the great library!
(used generator<> and recursive_generator<> with great ease and hapiness :-) )
