Comment(by jinmei):

 One more thing: while I believe it's better to keep running even if a
 systm level error (file is non writable, etc) occurs with logging, it
 would also be nice if we could report the error in some way.  In
 particular, if stderr is writable, reporting it there at initialization
 time would be helpful (an error that happens in writing logs may not be
 effectively reportable, but I think we can live with that).

 Dying due to an error for an optional feature isn't good, but silently
 ignoring errors is not good either.
