@clebertsuconic I've mentioned Netty just as an example of a event loop
framework that doesn't handle well recursive submits into the event
loop/blocking call issued from without the event loop.
The fix (if i'll remove the other changes) is simple: i'm just checking if
the call will happen inside the event loop: let me push it and you can see it
by yourself :+1: ---
