Unfortunately, the interfaces to the asynchronous facilities vary
greatly between platforms.  I've found that polling is rarely enough.
(MzScheme actually provides some functionality to interface with
asynchronous facilities.  It's a good start, but needs work to be made
more Scheme-implementation-agnostic.)

While this is an issue that's clearly worth addressing, it's not clear
to me that it needs to be done in this SRFI.
