"stopping server" logs not always visible

when invoking `/etc/init.d/influxdb stop`, all messages from https://github.com/influxdb/influxdb/blob/ffbe9be48a00e3e8361af0180b9237f05bb5d0a1/src/server/server.go#L212-242
should appear in the log, but this doesn't seem the case.
i suspect this is a race, the `log.Info()`'s are probably called correctly but the server exits before the records get written to the log.
I made sure to edit influxdb-daemon and to redirect all stderr/stdout to a file, so that if it panics, i would see it there (see #650), but the daemon records no stdout/stderr, implying a clean exit.

all the snippets below are the tail of a log, after calling `/etc/init.d/influxdb stop` and confirming the process is no longer running.  It seems pretty arbitrary how much of the log messages make it into the log.
