Maybe. I'll check this.
By the way: a concurrently running "while true; do sync; sleep 1; done"
did not change the beviour. Especially the stops did NOT occure in
second-intervals. Does this mean anything?
And: the data has to be written sometime. Isn't this possible without
disturbing capture? How should the syncs be done?

Regards,
        Ralf
