Strange behaviour when using -DFOREGROUND

[Bachsau <web@xxxxxxxxxxxx>]

Hi! I just installed Apache 2 on my Arch Linux Desktop machine for 
testing purposes and instead of running it as a system wide service 
through systemd I run it under my default user session whenever I need 
it, using the following command:

  /usr/bin/httpd -d "$HOME/Webserver" -f "$HOME/Webserver/httpd.conf" 
-DFOREGROUND

Of course I did setup a working environment for it there.

Now I switched my configuration to use mpm_prefork and discovered a 
strange behaviour which I do not understand: Whenever stopping a server 
(by using -k stop or SIGTERM) started with -DFOREGROUND through a 
.desktop starter, it not just kills the server and its children but my 
whole desktop session, throwing me back to the display manager's login 
screen. It does not happen when the commands are executed from a 
terminal window.

Does anybody know why this happens? Is it a bug? It thought DFOREGROUND 
should just keep it from detaching from terminal, therefore being a 
harmless option.
