commit 234b0f02a954928c54485c38ef37126ba5197597
Author: Tom Rondeau <address@hidden>
Date:   Fri Jun 14 18:15:50 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).

    runtime: (dup of e0f9a39 for 3.7 structure) making block_registry 
thread-safe for multiple flowgraphs to access it.
