Currently sync mode only affects components with a single input. Multiple inputs are processed in separate goroutines, so they are still async to each other.
Enforcing a StateLock mutex on all sync components would fix data races, but it wouldn't fix the "events order" problem, i.e. it doesn't guarantee the correct sequence of invocation.
It could be fixed by using a traditional Go's switch on multiple channels, but it is impossible because the list of channel variables isn't predefined.
