Uhm, find the cause. I already mentioned I had dropped the old
lock code. Well, I had missed to check one case it handled. When
user issues "quit" in interactive-mode, ecasound objects should
be properly deleted. With the recent CVS-tree version, ecasound
just exited right away after the "quit" command. This affected all
objects, but was especially annoying for wav-files, because their
header data is updated during object descrution (... which never
happened).

This was the critical part of the debug output. No messages about object
desctruction... now after fixing the problem, you get what is expected:

--cut--
ecasound ('h' for help)> q
(eca-main) ecasound_queue: exit!
ECA_PROCESSOR destructor!
- [ Engine/Exiting ] ----------------------------------------------------------
Exiting...
ECA_CHAINSETUP destructor!
ECA_AUDIO_OBJECTS destructor!
(eca-audio-objects) Deleting chain "default".
CHAIN destructor!
(eca-audio-objects) Deleting audio device/file "new.wav".
(file-io) Closing file new.wav
(eca-audio-objects) Deleting audio device/file "null".
--cut--

Once again, big thanks for the bug report!
