[visionegg] VisionEgg and Threads?

Hi,
we are trying to run VisionEgg in a threaded environment to integrate it with our current Brain-Computer-Interface system. We are using the python threading module in order to let VisionEgg share memory with our data acquisition thread.
So far, we have not been successfull - VisionEgg doesn't like to be put into a thread. If we do so by calling p.go() from inside a python thread, the start frame of the graphical presentation is displayed but is not updating at all. If we call p.go() from the main part of the program and leave out threading, it works perfectly, but it blocks our other python threads - they just don't run.
Is VisionEgg unable to run in a threaded environment? Can anybody else see the issue? If you want, I can send a minimal code snippet that reproduces the bug.
We could of course put VE into a separate processes and send the data through sockets, but that somehow breaks the nice and easy way of just putting the objects we need into shared memory. 

Thanks for any ideas / inspiration,

Thomas
