See the readme :-).
Motivation is allowing Snikket admins to change circle avatars via
the web portal without bypassing Prosody access checks.

This module compares the memory usage reported by Lua before and after each event and reports it to the log if it exceeds the configuration setting `log_memory_threshold` (in bytes). ``` lua log_memory_threshold = 20*1024 ``` If you are looking to identify memory leaks, please first read [Three kinds of memory leaks](https://blog.nelhage.com/post/three-kinds-of-leaks/). Prosody runs on Lua which uses automatic memory management with garbage collection, so the numbers reported by this module are very likely to be useless for the purpose of identifying memory leaks. Large, but temporary, increases in memory usage can however highlight other kinds of performance problems and sometimes even provide hits for where to look for memory leaks.
