Hi Roger,

Is it OK to have erlang:system_monitor permanently enabled in production?

One problem with `erlang:system_monitor/X` combined with an option such as
is that, for each GC, the C equivalent of `erlang:now/0` - which has some
very well known overhead - is called before and after each GC:


In other words, keeping long_gc monitoring enabled will add a couple of
sync points for each GC.

Disclaimer: It was not me discovering this, but a colleague, so not taking
any merit or blame for the discovery.
