Comment:
I've started work on this, and have the threaded RTS's IO manager thread
successfully using either poll or select, depending on the system.
This step alone is a big deal, because select has a low fixed limit on the
number of file descriptors it can manage, usually 1,024. Using poll
instead removes that limit.
There is a lot more work to do, but this seems like a good start.
