From my previous testing this won't give much improvement because while the application waits for IPC we have the main b2g process consuming pretty much all available CPU time, so the device is not really idle. However this does not mean that this bug is unimportant: most of the devices we use have single-core processors but this might give an improvement on dual-cores devices where we should effectively have some spare cycles while waiting for the main process to respond.

Thanks for your input. I'm doing a writeup on this in bug 997420. Suffice it to say, even if this provided some benefits, the work in that bug will make the work here irrelevant anyways. I think it's best to just jump straight to that bug.

Based on further research in bug 1001467, I don't think there's anything we can do here.
