[erlang-questions] An answer: how does SASL know that a process died?

This could be improved by making it work in the same way as undefined
functions etc.: by defining that a particular function in the
error_handler module gets called with the error information as
arguments. Then the formatting and sending to error_logger can be done
in Erlang code, making it much more transparent and easier to change
what it does, and no longer hard-coding a connection in the VM between
process termination and a high level service like the logger. You can
even avoid the whole send operation if you just want to drop these events.
