    Fix multilock concurrency when shared by > 1 threads

    Instead of raising thread errors when another thread
    has locks that the consuming thread wants to use just
    block and wait and release the correct locks on release
    to match the expected vs observed behavior.

    This makes it so that a single multilock object can be
    shared by many threads and each thread using the object
    will correctly obtain and release as expected...

    Fixes bug 1371814
