That's very interesting. Should we avoid it? It's a tradeoff between the
nice features, flexibility & integration using the OTP error logging
mechanism gives us and the overhead of same. I'm sure we could gin up a
sane logger that's much quicker (but less flexible) fairly quickly.

What if, instead, we used syslog? Or simply logged everything only
through an internal exchange, avoiding the error_logger?
