I think the docs are wrong, or perhaps we're misunderstanding them.
Magnus is correct.
Attached is a test program which listens on two ports, 42000 (blocking
IO) and 42001 (non-blocking). You can use netcat, telnet, etc, to send
it data. The behavior is as Magnus describes: bytes from
hGetNonBlocking are available immediately, while hGet waits for a full
buffer (or EOF) before returning.
This behavior obviously makes hGet unsuitable for enumHandle; my
apologies for not understanding the problem sooner.
