Damn... didn't go through... ;-)

I just encountered this one:

	http://www.dovecot.org/list/dovecot/2007-July/024059.html

which seems to indicate that a fchmod(fd, -1, -1) appears to fail on  
some NFS/OS combinations.
As a result, I'm not sure whether entirely hiding the log message is a  
good idea; perhaps just change the logging level would be better, so  
that one keeps the ability to track possibly problematic file systems...
