Does syslog have an internal buffer?

There is no internal buffer in glibc for syslog messages.  It would
not make sense, as the programs syslogging might terminate before the
syslogd is available to receive any messages.

Interesting idea, but I'm not sure how useful it would be.  I
recommend starting syslogd sooner in the boot process instead.
