``mitogen_get_stack`` action that is automatically added to the action
plug-in path. See :ref:`mitogen-get-stack` for more information.
* Multiplexer threads are pinned to one CPU, reducing latency and SMP overhead
on a hot path exercised for every task. This yielded an 8% speedup in a
64-target job composed of many short tasks, and should easily be visible as a
runtime improvement in many-host runs.

longer wait for indication of readiness from the OS to transmit data, and
instead assume transmission will probably succeed. As this is often true, one
IO loop iteration and two poller reconfigurations are avoided for many
messages, yielding a significant reduction in interprocess round-trip
latency.
