commit 149d6a75466cf052ef53f6f2d6bc276acb0991bd
Author: Tom Rondeau <address@hidden>
Date:   Sat Jun 15 16:47:45 2013 -0400

    runtime: 2 threading issues with the shared memory system.
    
    1. Making a global mutex for the VM circular buffers to use and lock for 
multiple top_blocks to handle accessing the memory.
    
    2. Catch the bad_alloc exception once and retry. After 1., this rarely 
happens unless the thread count gets large (> 20 as an estimate).
