[DEFER] Ext.lib.Ajax.request, why use Ext.applyIf(me, options) ? it make some leaks.

[cyrilluce]

In Ext.lib.Ajax.request, it copy some properties from options to itself, and some never used but always keep.

For example, the store.load will call with reader in options, if that's no 'reader' on Ext.lib.Ajax (applyIf)
It will keep it, and cause some leak (reader ref store, store's listeners maybe ref components, etc)

Is there any other reason use Ext.applyIf(me, options) ?

[Condor]

It's needed to be able to specify some header related request options.

But it should be replaced with Ext.copyTo to avoid memory leaks like you described above.

ps. I'm moving this to bugs.
