What is a ruby thread?  A green thread?  A kernel thread?  A green 
thread mapped to a kernel thread?

The depiction at the link somewhere above seems to suggest it is a green 
thread which is mapped one-to-one to a kernel thread.  Some here suggest 
there is no such thing, just kernel threads.  I will assume it is a 
kernel thread unless you say otherwise.

Actually I like fibers quite a bit, I just didn't think they were 
applicable in this particular circumstance.  I can check into neverblock 
- thanks.
