Richard Purdie b306d7d9a4 bitbake: server/process, server/xmlrpc, runqueue: Use select.select() on fds, not time.sleep() 
The existing backend server implementations were inefficient since they
were sleeping for the full length of the timeouts rather than being woken when
there was data ready for them. It was assumed they would wake and perhaps did
when we forked processes directory but that is no longer the case.

This updates both the process and xmlrpc backends to wait using select(). This
does mean we need to pass the file descriptors to wait on from the internals
who know which these file descriptors are but this is a logical improvement.

Tests of a pathaolgical load on the process server of ~420 rapid tasks
executed on a server with BB_NUMBER_THREAD=48  went from a wall clock
measurement of the overall command execution time of 75s to a much more
reasonable 24s.

README 

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.

For information about OpenEmbedded, see the OpenEmbedded website:
    http://www.openembedded.org/

Where to Send Patches
=====================

As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.

bitbake:
    bitbake-devel@lists.openembedded.org

meta-yocto:
    poky@yoctoproject.org

Most everything else should be sent to the OpenEmbedded Core mailing list.  If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
    openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix
      of oe-core and poky-specific files.
