massive memory leak in Flex

[Jason Taylor]

I believe I have finally identified the cause of a huge memory leak in our 
application, and it appears to be s:label
I have tested this on many different framework versions.

Please try the following:    if you make a custom itemrender and don't use the 
s:label it goes away, note disabiling TextLineReycler has no effect.  

Using task manager, scout, and IntelliJ Idea Flex profiler all confirm the 
memory leak.  This seems like a massive issue and has been causing a lot of 
slowdown and crashes in our app. I'm guessing I must have messed something up 
somewhere as I don't see how sucha  massive issue could have been in the 
framework for soo long (Tested 4.13, 4.14, and 4.15).  Please Advise.
