Supplanting BCI solutions

[Kasra Faghihi]

Hi,

I maintain an opensource BCI coroutines/fibers tool for Java:
https://github.com/offbynull/coroutines. I know you folks have many fancy
things planned for this feature, but here's what me (and many of my users)
would like to see...

1. suspend/resume a callstack
2. user-level manipulation of the lvts and operand stacks in a suspended
callstack
3. serialization  and versioning support (aka checkpointing) of a suspended
callstack

Item 3 may be a bit of a stretch, but as long as item 2 is available users
can implement this themselves.

Right now, my tool implements all 3 items. The best case scenario for me
would be to deprecate the tool entirely in favour of this new feature. Let
me know if I can help in anyway.
