Fixes a formatting problem that snuck in with gh-287, whose CI ran
before we added the formattin...

Faster ParkingLot

Add nursery.start and nursery.start_soon

The new 0.17 release has slightly different ideas about formatting.

Like right now, ctypes is broken, so pip just crashes:
https://travis-ci.org/python-trio/trio/...

start_soon is just a new name for spawn, except it doesn't return the
new task (in preparation f...

[ci] Print more info to hopefully get some clue what codecov is doing

Add deprecation framework, and do some deprecations

Refactor UnLock -> ConflictDetector

Part of the changes for gh-68

Also keeps run_in_worker_thread around as a deprecated alias.

By default they're unstyled and don't jump out at all.

Fixes gh-291.

Just rename it and make it always do ResourceBusyError, since that's
how it's always used.

These were broken before, but the socket -> _socket transition
revealed them.

This removes some kluges from trio._core._exceptions, and also fixes

Should rearrange the tests a bit too, but this gets rid of the

Stop acontextmanager coverage from flapping all the time

We have too many ways to close things; remove the redundancy

Fixes gh-140

Even if it fails, the contract is that it's done its best and there's
no point in trying again.

This also fixes some coverage that got dropped by the removal of
forceful_close.

There was a weird redundancy where there were 3 ways to close things:

- forceful_close: ungrace...

Remove stray print() call

Doh.
