I'll take a closer look - sounds interesting. What put me off
originally is that there is a heck of a lot of code there, which tends
to mean there's a lot going on whereas I wanted minimal impact and
control over blocking the client (or better, making the work in the
client) or not. Fastlog is only 665 lines of code, as it does very
little work to get from the call site to the underlying logging module
(error_logger by default).
