FYI, I don't think cross-context particles were ever working right. That was an item on our "to-redesign" list, probably for 2.5.

Fair enough. I'm seeing "random" testresults, f.i. for the Particle
destroy test, sometimes segfaulting, sometimes passing, sometimes failing,
and this _seems_ to be fixed with this patch. But of course this kills
performance too much. I just thought I'm missing some critical part of the
code where it should magically work ;)
