Add recommendation that fio be run in a native console on Windows.
Windows console applications often don't run correctly under Cygwin shells such
as mintty because of the way they're implemented. Add a recommendation to the

to avoid these problems.

Taking a look to the debugging output shows that on write action the
'fileno' variable is always set to 5 regardless of the file that should
be written. However, for open and close we have a different fileno value
for each file. Taking a look into the source code of read_iolog2()
reveals why: In case of actions 'open' or 'close', 'fileno' is looked up
through 'get_fileno(td, fname)', but for 'write', 'read' and the other 4
argument actions 'fileno' is not looked up. When I add a 'fileno =
get_fileno(td, fname);' at the end of the '(r == 4)' branch, I/Os are
replayed to the designated files.

net engine: implement option "nodelay" for TCP sockets
With disks, O_DIRECT effectively bypasses all buffering/caching mechanisms and
ensures that the I/O is going directly to the disk. Since TCP is a streaming
protocol (like disk I/O), it also has a buffering mechanism. As with disks, it
is sometimes desirable to bypass buffering. To that end, we can use
TCP_NODELAY, which transmits the packet as soon as data is assembled,
regardless of whether it occupies a full frame.
