You could just leave this thread running until it's done and meanwhile
start another thread. The first one shouldn't take too long, and even
if it does, in general there shouldn't accumulate that many concurrent
threads given that a normal user takes more time to think than a
computer.

If the user asks to do this then it could all be concurrent. It does
have to be threadsafe, however.
