-Note that the SVID goes into some detail about the expected behavior for
-different cases of MIN, TIME, or both equal to zero, so if the read blocks
-in the above circumstance the system isn't SVID-compliant.

How about someone in the know clarifying the behavior for the various
combinations of MIN and TIME for those of us who don't have easy access
to SVID?  This has always been a confusing issue...
