% The following line looks WIERD but its purpose is to delay this job for
% a while and cause lots of garbage collections (typically a couple of dozen,
% taking around 30 seconds on my reference computer). This gives time for
% the random number generator in CSL to seed itself a bit better. The user
% might like to run other applications, move the CSL window and otherwise
% generate events while this is going on! As an alternative the user can
% provide an explicit initial key via -Ddemo_key=nnn+mmm and take full
% personal responsibility.
