[9.0] TC doesn't stop background WFX copy on close

[MVV]

Why doesn't TC stop background WFX transfer operations on close? I tested it with my Virtual Panel, I've started copying some files from it to normal folder with background option enabled and then closed TC, and it simply called FreeLibrary for the plugin w/o stopping transfer first.
Of course I can add a code to prevent such unexpected terminations but I believe it should be done by TC and not by every plugin.

I think it's done to not further delay then closing of TC.

But it causes exceptions in plugins... Such unsafe things may not be left as is on TC closing, transfers should be terminated anyway.

Well, unloading a library for a still running thread must cause some catastrophic error... What's worse, we can't be sure about a data integrity for the background operation.

Maybe the transfer could be moved to foreground when trying to close TC?

Or even explicitly disable closing with background transfer.

TC could show abort confirmation for such background transfers. However TC doesn't show confirmations for aborting WFX transfers at all.
