Yeah, but your example is designed specifically to only encounter the
signal in one specific spot (inside a D function).
but I'm not sure how reliable it is. A more
conservative implementation would be something like
```d
extern(C) void handleCtrlC(int)
{
import core.stdc.stdlib: exit;
import std.stdio: writeln;
try throw new Exception("Killed by CTRL+C");
catch (Exception e)
{
writeln(e.message);
writeln(e.info);
exit(1);
}
}
```
This too is not going to be a good idea. writeln(e.info) is going to
possibly start allocating. A signal can come at any time, even when
locks are held or things are in an intermediate state.
I use Adam's approach normally -- set a flag and act on it later.
