Comment 19 for bug 1868486

Mark's tests fail for me as expected when added to the 3.15 branch on both MacOS and Linux, but not on RTEMS-pc386-qemu. RTEMS uses a different implementation of osdMessageQueue, as does VxWorks. Applying a reversed version of Ben's patch then results in some build warnings (status is never used) which I will clean up, but no test failures.

In comment #8 above Ben suggested:

My guess is that the equivalent situation for sends would be that the queue is usually full, and the timeout to a send request that is waiting to be queues expires at about the same time that the receiver takes an item off and wakes up the sender. This is probably a much less common scenario, but until someone writes a test that proves that we have a bug there I don't particularly want to make the other change.

For now I will not do any more than is described above. Additional tests proving the other change is also required would be welcomed.
