SIGINT is not delivered to processed launched from dmenu
Hello!
I've found strange behavior of processes launched from dmenu.
Here are the steps to reproduce:
1. Launch sleep 1000000 using dmenu. The key combination for dmenu is Win-D on my system. I believe Alt-D is the default one.
2. Execute pgrep sleep from shell to get a pid for process launched in step 1.
3. Execute kill -2 $(pgrep sleep).
4. Nothing happened. The sleep 1000000 process is still running.
kill -2 is working perfectly when I run sleep 1000000 process from shell.
What kind of magic is done by dmenu to block SIGINT from being delivered to processes? Is there any way to disable it?
PS. I'm using i3 metapackage of version 4.7.2-1 in Ubuntu 14.0.4.
Further investigation shows that dmenu isn't guilty. I've created sleep-999999 script with sleep 999999 & and put exec sleep-999999 on a hotkey in ~/.i3/config. This setup reproduces strange behavior described formerly.
