I mean non-canonical here. *ups*

And this is from the libc documentation:
http://www.gnu.org/s/libc/manual/html_node/Noncanonical-Input.html#Noncanon=
ical-Input

17.4.10 Noncanonical Input
...
Both MIN and TIME are zero.
In this case, read always returns immediately with as many characters
as are available in the queue, up to the number requested. If no input
is immediately available, read returns a value of zero.
