Signals

[Robbin via Digitalmars-d]

I'm writing a daemon in D on linux.  I need to be able to stop 
(kill) it. The traditional C method is a signal handler.  I can 
do this, but I can't figure out how to get the handler to do 
anything to tell the rest of the daemon to quit.

In a C++ handler, I closed the files that were open, removed a 
PID file and exited.  Nothing complicated in the job.  It was 
more complicated in the implementation - I did a longjump from 
the signal handler to execute the cleanup code.

I would love to setup "std.signals" classes and from the 
"core.stdc.signal" signal handler call "std.signals" emit() to 
trigger the "std.signals" observer.

Is there a canonical D way of catching a SIGTERM and unwinding 
everything?
