Yes, but it wasn't intended to be a criticism. In 99,999% cases it will work, and this is how I usually write it too. But since I had just bumped into the issue, I thought it might be interesting for people that just started with Erlang and the concurrency related thinking isn't very settled yet.

Another thought: this is such a widely used pattern that it might place in a standard library!?
