Ok, the Guile manual description leaves it a ambiguous. Even the R6RS
wording could be graciously bent slightly to support the age-old
nonblocking semantics. It boils down to what bytes are considered
"available." I don't think any nonblocking application would mind those
functions returning immediately with what they managed to read.
Thanks for the answer.
