Thanks for reviewing!
AFAIK we cannot restart stream if it's finished, so we have a race condition of 
main loop and callback caller.
Resolving this race condition would make code much more complex for a 
relatively small benefit.

I'll address typos in next patch version, thank you for looking into this.
