Force Lua garbage collection before p3DEngine->UnloadLevel() and pRenderer->FreeResources(flags) are called.
p3DEngine->UnloadLevel() will destroy particle emitters even if they're still referenced by Lua objects that are yet to be collected.
(as per comment in 3dEngineLoad.cpp (line 501) - "Force to clean all particles that are left, even if still referenced.").
Then, during the next GC cycle, Lua finally cleans up, the particle emitter smart pointers will be pointing to invalid memory).
Normally the GC step is triggered at the end of this method (by the ESYSTEM_EVENT_LEVEL_POST_UNLOAD event), which is too late
(after the render resources have been purged).
This extra GC step takes a few ms more level unload time, which is a small price for fixing nasty crashes.
If, however, we wanted to claim it back, we could potentially get rid of the GC step that is triggered by ESYSTEM_EVENT_LEVEL_POST_UNLOAD to break even.
