Closing TC while bkgd copying - files not removed

[Flint]

1. Start copying of some large file in background thread.
2. Close TC. It will warn about the background thread, press "Yes".
3. The destination file that is now incomplete is not removed, though if you stop the copying manually TC removes the destination file which is not copied to the end.

Besides, no item is added into log file about such copying termination.

When you click YES, the background thread is terminated in a hard way, no cleanup is done at all.
