8 Registers a function to be called after an error occurred during request handling and the error response has been prepared by filling the "trace" and "system_error" slots in request.handler(...). The registered handler may, for example, send an error report to an administrator (utilizing slot.render_layout(...)). The passed handler function gets the error message (or error object) passed as first argument and the stacktrace as second argument.
