So to render two pages I will have to make two fork() calls? It means
that on two-processor machine the speed of rendering two pages will be
the same as speed of rendering single page? Awesome!

please schedule that. If I happen to do it first, I will quickly inform
you about that.

Problem is that I cannot predict my time-availability. But if you can
give a few more explanaintions on how I should try to do this I will
feel more inclined to do it :)
I see it as:
- add widget page1, make sure that it is displayed in correct place
- attach second gs interpreter to that page, and then keep the pages
synchronized.
for now I prefer to ignore a bool flag that will enable/disable two
paged view. Too much complications :)

aah! that explains why upon renaming page into page1 I had some strange
problems with respect to page widget.
