Replace the naga.cpp in sry folder before install to test
I have this github project :
https://github.com/lostallmymoney/Razer_Key_Mapper_Linux .
To replicate this bug you can install and launch it by running sh install.sh ,
next open a terminal and run naga -restart .
Restarting the daemon causes a bug with system('command') wich makes it not
launch the command and gives the PID 0. You can test the code with this file so
it tries to use system right after -restart. Here's the edited file :

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85226 --- Comment #6 from f-rog at hotmail dot com --- Well my bad it's a bug that made it so i needed to wait at least around 20 ms before restarting the daemon. It's weird tho because i could press the button and get the log : Command executed : command and yet i'd need to wait like 1 second with the key pressed for it to actually do anything. If I released it was like it had never ran the actual thing. I still think somehow it's a system() related bug but I patched it.
