"""Thread pool that doesn't immediately queue all items.
The default (Thread)Pool class will always have a non-blocking
apply_async() function. This means that while we're looping over
the queue of files to copy, they are all popped off that queue
and turned into async tasks. That means that when there is an
error, the queue is empty and we don't have a reliable
"these files were not transferred" list.
This class will block when all threads are in use.
