[linear2] fix MuxProcess test fixture and some merge fallout
service: avoid taking another lock in the usual case
service: don't acquire lock when pool already initialized
profiler: marginal improvements
core: ensure 'exit' signal fires even on Broker crash.
core: wake Waker outside of lock.
core: wake Latch outside of lock.
core: remove old blocking call guard, it's in the wrong place
Make setting affinity optional.
ansible: abstract worker process model.
[stream-refactor] parent: fix crash on graceful shutdown
parent: tidy up create_socketpair()
core: more concise Side.repr.
Given:
- Broker asleep in poll()
- thread B calling Latch.put()
Previously,
- B takes lock,
- B wakes socket by dropping GIL and writing to it
- Broker wakes from poll(), acquires GIL only to find Latch._lock is held
- Broker drops GIL, sleeps on futex() for _lock
- B wakes, acquires GIL, releases _lock
- Broker wakes from futex(), acquires lock
Now,
- B takes lock, updates state, releases lock
- B wakes socket by droppping GIL and writing to it
- Broker wakes from poll(), acquires GIL and _lock
- Everyone lives happily ever after.

Move all details of broker/router setup out of connection.py, instead
deferring it to a WorkerModel class exported by process.py via
get_worker_model(). The running strategy can override the configured
worker model via _get_worker_model().
ClassicWorkerModel is installed by default, which implements the
extension's existing process model.
Add optional support for the third party setproctitle module, so
children have pretty names in ps output.
Add optional support for per-CPU multiplexers to classic runs.
Now it's possible for stream.protocol to not refer to MitogenProtocol,
move the signal handler to a MitogenProtocol subclass instead.
Fixes a crash where CTRL+C during child bootstrap would print
AttributeError.

During early initialization under hackbench, it is possible for Broker
to be in LogHandler._send() while the main thread has already destroyed
_buffer. So we must synchronize them, but only while the handler is
corked.
