We recently changed from signal(2) to sigaction(2) and some IO related syscalls started failing with EINTR.
Reading the different manpages, BSD changed signal(2) to have SA_RESTART semantics, which glibc on Linux followed by not calling the signal syscall but instead calling sigcation with the SA_RESTART flag.
