The standard implementations of syslog lose log entries under heavy
load, because they rely on a daemon which reads from a named pipe with
a limited buffer space.  This is not acceptable in a production
system, since heavy load is often just the time you need to see the
log entries.

It would be possible to implement the syslog(3) interface in a
different way, of course, which did not use syslogd.  I don't know of
any such implementation.

(My personal preference these days is an approach like DJB's
daemontools, which separates the handling of log entries from the
program doing the logging.)
