Log message:
Improve channel ring locking strategy
Make sure to hold the ring buffer lock for the complete duration
of a channel ring I/O operation. For read operations this means
peeking and reading is done uninterrupted and for both reads and
writes this places the buffer space availability check under the
same lock as well.
