It doesn't "return", but it does call a number of user-specified callback
functions at regular intervals, so the application can gain control at regular
intervals. However, the handle can't be transferred to a different thread at
this times because the call stack ends up going through curl functions. What
you appear to want to do can probably be done with the multi interface, as that
does actually return to the application regularly. You would have to be very
careful, naturally, and this isn't a recommended use case, but it would
probably work.
