Test was inconclusive. Interrupting getaddrinfo() with a non restarting signal executes the signal handler and automatically restarts the blocking call (probably recv() ) so EINTR is not being returned.
It's likely that the glibc implementation of getaddrinfo() is just restarting the call itself. I think it still makes sense to test for EINTR regardless.
