mod_post_msg: Add sendxmpp-curl I wrote this script around the same time as this module. My local copy has a last modification timestamp of 2011-03-29, so it's been unchanged since then. The original rationale was that it seemed overkill to establish an entire XMPP session just to send a single message. Nowadays I'm quite happy using `clix` for this kind task.

This module logs events where more than a certain amount of CPU time was
spent.

``` lua
log_cpu_threshold = 0.01 -- in seconds, so this is 10 milliseconds
```

Uses the Lua
[`os.clock()`](http://www.lua.org/manual/5.2/manual.html#pdf-os.clock)
function to estimate CPU usage.
