No. I tried this again to find out more. What apparently happens is
that Alsaplayer tries to connect to jackdmp, it succeeds (shows up
in qjackctl and is connected) but somehow it thinks it fails and
then opens the ALSA interface on hw:0. So it ends up with two output
methods calling the main code.

So now there are two questions:

- Why does Alsaplayer wrongly think it can't connect to jackdmp ?
- Why, if that happens, it falls back on ALSA while the user has
  clearly requested to use JACK ?

Aaaaaarrgggh !


Apart from this there are two minor problems:

- I get a jackdmp error whenever an application
  terminates - a write to a fifo fails. It seems
  to happen with all applications. 

- The install remove target fails if you happen to have
  a old libjack.so around. I had both 0.0.23 and 0.0.27
  installed, with the symlinks going to latter of course,
  and the remove target tried to restore the wrong one.
