Sounds great. Looking forward to it.

For the multiple threads implementation will you be rolling your own
scheduler and locking primitives or relying on a thread library provided
by the operating system? What types of primitives will be provided to
S-Lang scripts? (ex: thread_create(), mutex_create(), ...)

Yeah. I'm guessing you will have to have separate entry points into the
library for thread away applications.
