my code forks off a child which does the actual libcurl stuff, so the main
parent can continue to be responsive to the user. when we need to stop the
transfer, send a signal to the child process, which will catch and exit,
then the parent can exit.

there are other ways too, with multi-threaded programs and shared
variables, etc.
