Yes, this is the second surprise interaction between the CPU scheduler
and the IO system.
Perhaps. In your case it seems that you're simply unable to generate

It is not necessarily a bad thing (unless your total runtime has increased?)
but we need to understand what has happened.
What filesystem are you using?
