as3 socket with multi thread or background process in as3 socket - multithreading

Question

my project using flex mobile 4.5 using socket .. receive huge data stream..
and ui application like hang... in minute before all process data complete
and how to do with multi thread in socket in as3 ? any axamples ?
any trick? to make background process
bellow my code

Answer 1

If you are stuck with an old version of the flash player, you need to search google for "Green Threads in AS3".
If you are using a newer version of the player, or Adobe AIR for desktop and devices, multithreading, via "actionscript workers", is available.
