Norman Maurer 9f6e06dc43 [#3675] Fix livelock issue in MpscLinkedQueue
Motivation:

All read operations should be safe to execute from multiple threads which was not the case and so could produce a livelock.

Modifications:

Modify methods so these are safe to be called from multiple threads.

Result:

No more livelock.
