Otherwise the global event handlers accumulate, one added each time
logging is reoladed, and each invocation of the signal or event triggers
one dump of each created ringbuffer.

Summary
=======
Sometimes it is useful to get the raw XML logs from clients for
debugging purposes, but some clients don't expose this.
This module logs dumps everything sent and received into debug logs, for
debugging purposes.
