(I am speaking without measuring anything.)

I imagine that lost cache is one of the biggest costs in thread 
switching. It would be great if a thread could select a thread with 
something like "I'm done, now please switch to my reader". And that's 
exactly one of the benefits of fibers: two workers ping pong back and 
forth, without much risk of losing their cached data.

Is my assumption correct?
