Try core.sys.posix.signal. kill provides a list of signals via 
kill -L.

basically what you do, if I recall correctly (it's been a few 
years), is something like this:
```D
import core.sys.signal;

enum SIGSEGV = 11;
extern (C) void handler(int sig)
{
    switch(sig){
      case SIGSEGV:
        // handle sigsegv
        break;
    }
}

sigset(SIGSEGV, handler);
```
