It makes little sense to run dired-do-copy in a separate thread,
because the primitive functions it invokes don't run asynchronously,
and therefore the new thread will not yield to the main thread.  The
result will be that the main thread will be suspended for the entire
time dired-do-copy runs, I think.  Which is not what you want.

Ask the user for the directory before starting the thread, then wrap
dired-do-copy in a function which fetches the directory input by the
user from some variable.
