You either need some kind of non-blocking I/O, or you need
TDLL (Daniel Kluss) which creates a new O/S thread and returns
immediately. I assume it will be safe to run the Euphoria interpreter 
in one O/S thread, and some DLL code in another.

I'm not sure yet how multitasking is going to work with
Euphoria-coded DLLs. Main Euphoria programs and Euphoria-coded DLLs
don't even share the same routine ids. Probably a Euphoria DLL 
could run its own tasks independent from the main program.
