send messages to SPUs
gMidphaseSPU.sendRequest(CMD_GATHER_AND_PROCESS_PAIRLIST, (uint32_t) &taskDesc);
we should spawn an SPU task here, and in 'waitForResponse' it should wait for response of the (one of) the first tasks that finished
not implemented

tell the task scheduler to use no more than numTasks tasks
Implements btThreadSupportInterface.

| void PosixThreadSupport::waitForResponse | ( | unsigned int * | puiArgument0, | |

| ) | [virtual] |
check for messages from SPUs
We should wait for (one of) the first tasks to finish (or other SPU messages), and report its response
A possible response can be 'yes, SPU handled it', or 'no, please do a PPU fallback'
Implements btThreadSupportInterface.
