Could you pls run a test for me? In julipedia.c, pls change "/tmp/foo"
to "/tmp". Start it, and do some file operations in /tmp. What happens?

Here under Ubuntu, it crashes immediately. Seems to be another bug :-(

I've tried to downgrade libkqueue0 from 2.0.3 to 1.0.4, but same problems ...

TIA, and best regards, Michael.
