This is like teaching users of SBCL that sending a SIGTERM to a process 
is going to ask it to terminate. This is not SBCL's domain, but that of 
the operating system that SBCL runs on.

The SIGQUIT behaviour is defined by libc, see 
https://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html#index-SIGQUIT. 
That's where the user should look to learn about the behaviour and how 
to prevent it.
