There is definitely no way to fake SELECT using the Scheme 48 port and
channel system. The reason is that they only way to test for writing
is to actually *perform* a write. There is no equivalent to char-ready?
even inside the system. So all I can offer is to use the select
syscall with a short timeout and then do a loop until something
happens.
