I'm writing an application, a photo viewer, that shows a 2x2 matrix of
Internet WebCams by continually redisplaying JPEG images over and over. This
is done by using 4 threads all running at once.

        I keep seeing references to CURLOPT_NOSIGNAL, but I want to know if it
*must* be used. Problem is that when the timeout doesn't trigger, all the
cameras can get hung up because every minute or so I require that all threads
be killed and if the easy_perform() function hangs, the whole app hangs.

        With the assumption that if one cam has a DNS timeout, say, then it's OK for
the other cams to be interrupted by a SIGALRM, would it be fair to say that
the CURLOPT_NOSIGNAL option is not *required* for multi-threaded
programs--only ones that would be affected in a bad way if all the threads
were interrupted?
