Richard Purdie a87aa7b7af bitbake: process: Improve _logged_communicate buffering 
There are two problems with the _logged_communicate that are both
caused as a result of buffering I/O issues:

1) log truncation when python fails

2) While a bitbake task is running it is impossible to see what is
   going on if it is only writing a small incremental log that is
   smaller than the buffer, or you get only a partial log, up until
   the task exists.  It is worse in the case that stderr and stdout
   are separate file handles, because previous code blocks on the read
   of stdout and then stderr, serially.

The right approach is simply to use select() to determine if there is
data available and also flush the log before exiting.

This is based on a patch from Jason Wessel <jason.wessel@windriver.com>
with some changes to flush upon exit, abstract the non blocking file
descriptor setup and drop the buffer size parameter.

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.
