Can I control the memory limit (i.e. when GC has to run) in my Flex application?
回答1:
I don't think so. That is probably a parameter of the flash player based at the client, and I assume it is also dependant on the exact resources the client machine has, i.e. more RAM means less frequent gc, etc.
回答2:
Check out the flash.system.System class. The "totalMemory" property will show you (in bytes) how much memory the current application is using. Calling System.gc() will run a GC. You could use a Timer to periodically check totalMemory and then preform gc if it exceeds a threshold. More info:

I am not 100% sure, but I believe the answer is no. Read this article.
