bufsize will be supplied as the corresponding argument to the open()

And I get these results (on CentOS-6.5-x86):

| bufsize | results |
|---------+---------|
| default | hangs   |
|      -1 | hangs   |
|       0 | works   |
|       1 | hangs   |
|     >=2 | works   |

I tried -1 and 1 on my Lubuntu and it still works fine.
Definitely weird, it begins to look like a CentOS build issue
but what is CentOS doing different to Lubuntu/Suse/OpenBSD etc?

From memory CentOS is basically a free version of Red Hat
Enterprise Linux? I can't see why that would be significantly
different in stdin/out behaviour.

weirder and weirder
