I just learned about these c-level coroutines in this thread. I surfed a 
lot and read everything I could find about them. So therefore I think 
lua-only coroutines should be kept. For lua-only coroutines: (this is 
just what I read, I have no experience, so I may be wrong)

1. have no architecture dependency
2. use less memory
3. switch faster
4. setjmp/longjmp are reported to behave strange on some systems (or 
faulty implementations) -> otherwise you would need an asm part for 
every system.

Don't get it wrong I found the c-level coroutines great and having the 
choice to use them is good thing.

Best,
