I'm no expert on this matter, but from what I've read I'm quite sure that IPC is not the issue. It's about context switching etc., AFAIUI.
One version of L4 for Intel does a synchronous RPC including context switch in 400 cycles. Which is pretty damn fast.
Or, to steal one of the phrases Linus likes to say himself (but about other concepts): "If context switches are the problem, the solution is not to get rid of them, but to make them fast."
