New Revision: 20059

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=20059

Log:

james was asking about CAP_LARGE_READX and reads close to the 64k
boundary. This test shows that both for Samba4 and w2k3, reads larger
than or equal to 64k don't work (return zero bytes).

Not that I claim this is very useful behaviour :-)
