Reaper used with JackOSX

Using Reaper under JackOSX and specifically using the JackVST and JackAU plug-ins shows some problems.

JackAU or JackVST plugins are *strongly* connected to the underling JACK client (the one living "inside" the JackRouter device), and basically just add some send/return ports to it. If calling the JackRouter process function and calling the plugins process functions is not done in the same thread, then all sort of complex synchronization issues start to happens, at the audio level, but also can cause crash problems, if the JACK client inside JackRouter is closed while the JackAU or JackVST plugins are still there.

We have seen that Reaper seems to spawn it's audio code over several additional worker threads, where plugins process function are actually called. So this way of doing basically destroying the assumption JackAU or JackVST plugins are relying on to work properly.

It there any work around for that could be implemented at the plugin level?

Thanks.
