Cone is still compiled on relatively old platforms. C++11 is not a viable  
option right now; but probably in a little while this would be an option.

I do not see a good reason not to use an internal pipe, in non-blocking  
mode, and with O_CLOEXEC set. sig_atomic_t has been around only since C99;  
but I suppose at this time requiring C99 would be acceptable.

I would have to look at this closer, to determine the right answer.

No big rush here. You can take your time and test your changes thoroughly.  
In general, this looks fine but I have not had a closer look; but I will  
consider it. A few procedural things will need to happen for that; but that  
can be left for later...
