Or possibly have the program fork() and run the curl_easy_perform() in the child fork while
the parent process watches for whatever condition you feel warrants bailing out early...
Catching the bailout condition and sending a kill signal to the child process may not be the
neatest solution, but it seems to fulfill your requirements.

I'm assuming that cocoa & OS X allow fork and signals - I have no clue either way... :)
