Darn, from the javadoc of java.lang.Thread:

"The newly created thread is initially marked as being a daemon thread
if and only if the thread creating it is currently marked as a daemon
thread."

so what is happening is that equinox starts my bundles in a daemon
thread and hence, my threads end-up being daemons under equinox. In
other words, one has to always call setDaemon unless one doesn't care
- pff.

Sorry - didn't know about that one.

Karl
