Konstantin Belousov 8dad5ece49 dd(1): neutralize SIGINT while non-async-signal safe code is executing ... making the SIGINT handler (the terminate() function) safe to execute at any interruption moment. This fixes a race in 5807f35c54 where SIGINT delivered right after the check_terminate() but before a blocking syscall would not cause abort. Do it by setting the in_io flag around potentially blocking io syscalls. If handler sees the flag, it terminates the program. Otherwise, termination is delegated to the before_io/after_io fences.
