That's going to be rather dependant on your use-case. For ordinary call
bridging it has no need to. You could grep the source code to find out.
It'll need to any time you run an external process, such as when sending
email (I assume it's wrapping sendmail or similar?).

what can cuase system() to hang?

Since system() doesn't return until the child process is completed,
anything causing that child process to hang would.
