I ran into a very similar behavior as well. There is an ongoing discussion at ubuntuforums where I posted some info but I think it is better suited here. Here is the thread:

So this is on Ubuntu 13.10 with znes package version 1.510+bz2-5ubuntu3. Very similar behavior -- the application stops responding to input after 30 minutes or so and can only be SIGKILL'd. I ran strace on the hung process and it appeared to be stuck in a futex-based deadlock:

futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x9851848, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
