I think it'd be nicer, to let the plugins register for a `shutdown'
event, if they want to clean up behind themselves.  The
`plugin_register' function should be changed in the process, to allow
for a more generic interface. Something like this:
  int plugin_register (char *name, int event, void *callback);
Where `callback' is either cast to `void (*) (void)' for `init', `read'
and `shutdown', or `void (*) (char *, char *, char *)' for `write'.

Hm, that message should appear everytime collectd exists.. Are there any
errors or warnings in the syslog, if that message doesn't appear? I'll
try to reproduce this..
