Runtime-loaded images need to be “disposed()”  Set the source to null and let 
it validate or call validateNow().

I’m not sure about embedded image assets.  I’ll try to find time to look into 
that.

We’ve found two  remoteobject bugs recently.  One is that, on every call, a few 
bytes leak.  It isn’t that bad but if it causes fragmentation it can add up 
over time.  The other is that if you instantiate a new RemoteObject and try to 
get rid of it, you can’t and it seems to leak a decent chunk of memory.  I’m 
pretty sure the first bug will be fixed in 10.1.  The other was only recently 
reported so I don’t know if it will make 10.1, and most folks I hope aren’t 
creating and destroying RemoteObjects very often.

Thanks Alex,

I had gone around and around to get a certain module to unload and was unable 
to determine the cause.  Your article was very informative and my suspicion is 
that an image loaded at runtime was at fault.  But that really isn’t the same 
thing as compile-time embedded assets, is it?

As far as remote objects are concerned – if they are invoked via some sort of 
Command class, that should avoid this problem, am I right?

Jeff

In Flex 4, styles are “per-module” and thus much less likely to leak.  That’s 
the only change.  Everything else is the same.

Are you seeing evidence that embedded image assets are leaking?

Getting modules to fully unload has been something I’ve spent (wasted?) a good 
deal of time on in the past and I’ve just finished reading with great interest, 
Alex’s article on the subject:
http://blogs.adobe.com/aharui/2009/08/what_we_know_about_unloading_m.html

My question is – how much of this is resolved in Flex 4?  Because if most or 
all of the issues have been addressed, I’ll simply abandon my Flex 3 
development of module-based applications and move to Flex 4 right now, 
especially given that Flex 4’s release is imminent (early spring?).

Of particular concern is the bit in Alex’s article about unloading images and 
the fact that image assets could be loaded via Stylesheets, etc.
