Continuations example in "C" which can be used to implement async-only single threaded request servers over the age-old poll and multi-threaded dispatch mechanism.

Currently supported for x86_64 and i386 because of the way the closure is implemented which makes it arch. dependent.

But its simple to just change the closure to a standard "C" function pointer.

Check out continuation_test_{1,2}.c for sample usage and the source code for details.
