M:N threading is an unnecessary performance hack that's needed by people
who are living in a C or C++ exile away from some language that has
lexical closures, generators or first-class continuations.
Yes, that's called the "real world." Arguments of the "I don't need it,
in a perfect world you wouldn't either, therefore it's a bad idea" type
simply contribute nothing.
Because user threading can avoid context switches, there will always be
cases where it will outperform o/s threads for hardware reasons.
