The swap problem is analysed and the cause of the problem is well-known 
now. The result is that the pagedaemon deadlocks itself, and therefore
the system rather quickly runs out of pages. I have rewritten the page
table handling and I am currently debugging it (I found a bunch of other
problems while doing this).
Many thanks to Chuck Silvers that helped me to understand what was actually
wrong and pointed me in the correct direction for a good solution!
