Only recycle producers, if there's no data in queue.
...
("The queue" is per-thread partial queue here.)
This fixes a problem where one thread writes to the queue, then is
terminated, making the (partially filled) queue available for other
threads to recycle. If another thread re-owns the queue, it will change
the associated thread id, while part of the queue was filled by the
original thread. This obviously created invalid data during dequeue.
The fix makes the recycling process check not only for queue inactivity
(which is marked when the original thread terminates), but also if the
queue is empty, preventing mixing data from different threads.

Degrade ARM timer to monotonic raw clock.
...
The monotonic raw clock has the same accuracy as reading cntvct registers, but
using clock_gettime() has a measurable impact on queueing time (135 us vs
83 us).
This change is needed to enable ftrace time readings on ARM linux, which
doesn't provide any way to get raw cntvct readings, like x86-tsc on x86.
