Currently the greybus-loopback thread logic spins around waiting for send_count == iteration_max which on real hardware doesn't make a difference to us but in simulation is excruciatingly slow, anti-social and bad manners. Use the existing gb_loopback_async_wait_all() function to gate continuing when the send_count == iteration_max and go to sleep until there's something worthwhile to-do.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
