Other reasons: syslog is rumored to drop messages under sufficiently
heavy load (at least on some platforms); syslog inherently can't capture
all messages that might appear on stderr.  For example, on most
platforms a link failure in loading a dynamic library is going to be
reported by the dynamic linker on stderr --- we have no way to reroute
it to syslog.  If you're trying to debug a problem like "why doesn't
plperl work", those messages are priceless.
