-----------
2.5: rendering thread-safety experiment, when setting G.rt to 101, it will
render from a Main database created from the undo buffer. That means extra
memory usage and processing needed, but gives no interference with other
data.

Still won't work entirely since there are a few things that don't get
flushed always (editmode, sculpt, ..) and some places that use globals.
