I believe I already answered this question when you asked on irc. But
I'll answer it again so it can be logged.
To put it simply you are barking up the wrong tree trying to do
asynchronous things from a lua script.
Change your paradigm in your brain to think about it more like a GUI loop.
You only have 1 thread and you want to make the channel do something
by itself in the background but your script is already executing....
If you want this you need 2 threads. There are several ways to get
this but you have to choose one.
1) Use ESL and an external application that can be running in your own
process so you can perform async operations.
2) Send the channel to the "park" app but spawn your lua script with
luarun via the dialplan variable.
<action application="eval" data="${luarun myscript.lua ${uuid}}"/>
<action application="park"/>
Then use the uuid argv[0] as the arg to a new session constructor that
will hook the channel to your object and you can tell the channel to
do things as long as you only execute them async
session:execute("foo::bar")
Remember if you are not running the session in its own thread this
will block and the whole idea is sort of messy but its possible to do
this.. if you script dies for instance your channel will not hangup.
3) Write your program in C where you have full access to threads
etc..... (THIS IS THE BEST CHOICE IMHO)
