On some older OSes I see a few `fgets error` coming from criuengine restore function. They are intermittent and hard to debug. After replacing libc fopen/fgets invocations with open/read, the problem went away. I'm still not completely sure why the problem with libc file functions exists but I suspect that EINTR is not correctly handled there, or the fact we store a sequence in characters without `\0` or `\n` in the file we read. So I propose using the lower-level interface to read the file.
