polygon kills X-server

This one is extraordinary dangerous: it also killed my kind of X server
called Windows completely so that I had to reset the machine.

Perhaps it should be debugged on the Linux side with less serious side
effects....

The best way to debug this might be via a nested X server - something
like Xnest or Xephyr - or possibly on a virtual machine in the hope
that the virtual machine's display system crashes before the host's
does.

 I haven't tried this yet!
