Related to this, I watched a talk about user-level threads by
another Google engineer awhile back (also named Paul but not the
same person).

It's been awhile so I may have this a bit wrong but as I remember
it the gist was that OSes don't have enough information for
efficient scheduling and context switching of threads but if the
OS lets the application handle it the context switching cost
drops significantly (down to roughly 200ns).
I came across it while following some Rust development which was
a very interesting read:

It's a bit over two years old now so I'm not sure what path Rust
took.
