Error: blender 2.68RC1 r57908 windows 64 bit.
--- Short description of error ---
Hi.
The crash happens when rendering hair with the, 3D view: Shading mode: Rendered.
If you set many different properties like, object location, rotation, or hair settings.
Blender crashes with error report, or to desktop.
It seems to happen after sliding a property for an ammount of time.
If i disable the hair, the crash doesnt happen.
If i set Properties->Particle->Display to None or Path, it doesnt crash, it only crashes with Properties->Particle->Display is set on Rendered.
--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
Attached: quadapuss_01.blend
Open quadapuss_01.blend
Set 3D view: Shading mode to Rendered.
In the Properties_Editor, Object, Transform: Rotate the object with the slider, x, y, or z.
bug: crash or crash to desktop.

Confirmed, threading issue, updating particles wants tessface's while the objects modifiers are being recalculated.

The big issue we have with blender internal viewport render crashes is that it's doing scene conversion in a render thread, while for cycles this all happens in the main thread. I think either the code should reorganized to do the scene conversion in the main thread, or there should be some mutex lock used.
RE_Database_FromScene should also be split up then so that things like shadow buffers, SSS and volume precaching are done in the render thread still.
