* runtime: for blocks with a group delay, tag location should be moved ↵Tom Rondeau2013-10-291-1/+2
| | | | | | according to the delay. Since group delay is often unknown, we have added a new function set_group_delay to allow the user to set the value once delay is calculated. Also added ability to set the tag propagation delay, which is required for how the blocks::delay works.
* runtime: 2 threading issues with the shared memory system.Tom Rondeau2013-06-141-1/+10
| | | | | | 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).
