My problem is that when FileToCopyTask raises an error, the program does not

In fact when the error is Disk Full, I want to stop the whole program
because I know that the next task will fail too.
If you're starting a thread for every file you're copying, you're
starting a huge number of threads that probably will just end up
fighting over the disk. To get a reasonably efficient early-abort, I'd
recommend having a fixed pool of worker threads (say, ten of them),
and have each thread (a) check if the early-abort flag is set, and
then (b) start copying the next file in queue. Once the queue's empty
or the early-abort flag is set, all ten threads will terminate when
they finish their current transfers.
Yes, my example was simplified, but I do that :)
