Ok, I didn't consider the backend callbacks a "thread" in the usual sense. Nisse suggested (in my mailbox) that there could be several types of backends (that should be possible novadays, right?), and I certainly see how a special "fascist-backend" might be useful to some applications (such as Roxen). Apart from preventing access to blocking calls, it should probably restrict access to calls like exit() as well. :-)

Well, if it could detect busywaiting and infinite loops too it'd be even better. It would be very useful for the backend thread in Roxen, which must not do anything that keeps it from returning to the backend quickly.
