Another small bug found...
After discovering for myself that .au files can be easily cat > /dev/audio
I thought "lets try the same with midi files > /dev/sequencer". The idea
as such is quite silly, I admit, but here is what happened:
cat bridalm.mid > /dev/sequencer
Then looked in /var/log/messages:

And after this I tried to use playmidi and play some .mid files in a "proper" way. Playmidi hang in a non-interruptible sleep
("D" flag shown by top or ps -aux). Look, it is still running: (unnecessary lines deleted)
USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND

Interesting, huh?
