	threads on shutdown
2015-10-28	remove debug code	Joey Hess

2015-10-28	fix memory leak, and optimise when command output is very large	Joey Hess

2015-10-28	fix buffer order	Joey Hess
	Build it up reversed, and reverse when processing.

2015-10-28	fix tricky race	Joey Hess
	Race between 2 calls to takeOutputLock'. The first call empties the TMVar, and does some work to check it. Meanwhile, the second call could sneak in, see it was empty, and call waitlock. Since waitlock used tryTakeTMVar, that would not block it, and it would think it had the lock, filling the TMVar. In the meantime, the first call could decide it had to lock and go on to possibly cause trouble.
2015-10-28	fix bad MVar use, use STM	Joey Hess
	I had 2 MVars both involved in the same lock, and it seemed intractable to avoid deadlocks with them. STM makes it easy. At this point, the concurrent process stuff seems to work pretty well, but I'm not 100% sure it's not got some bugs.
2015-10-28	need withConcurrentOutput to flush any buffered concurrent output	Joey Hess

2015-10-28	propellor spin	Joey Hess

2015-10-28	propellor spin	Joey Hess

2015-10-28	use outputConcurrent interface	Joey Hess
	This interface will fix the current deadlock when a process is running and the thread that ran it wants to output to the console. The locking and buffering is not implemented yet.
