{color:orange}chan_dahdi-free_pfds.patch - I have doubts about this one. It seems safe since there should only be one thread working on pfds at a time, but I kind of feel that the thread should simply be responsible for cleaning up after itself in all paths rather than having a post pthread_join cleanup like this. Consider the use of pthread_cleanup_push perhaps? Alternatively just make sure that the thread can't cancel until it has taken care of pfds.{color}

{color:orange}main-asterisk-kill-listener.patch - I'm a little nervous about the use of pthread_kill here. A pthread_cancel has already been issued, so the kill should be unnecessary as long as the thread is guaranteed to eventually reach a cancellation point. If that guarantee isn't met, we need to make that guarantee be met rather than forcefully ending the thread this way.{color}
