xcape not closing unix sockets

[devonestes]

I'm super happy to have xcape to help make my keyboard do what I want, but I recently ran out of available sockets on my Linux machine (Ubuntu 18.04). For example, I'm seeing the below behavior:

lsof -U +c 15 | cut -f1 -d' ' | sort | uniq -c | sort -rn | head -3
    188 xcape
    126 dbus-daemon
     59 slack

Looks like there's a bug somewhere causing xcape to hold on to open sockets, keeping other programs from launching.

I can solve this by restarting, but I figured I'd report this behavior because others will surely run into this issue, too, and it's kind of annoying when this happens.

Thanks again for the great library!

    254 Xorg
    224 xcape
     92 dbus-daemon

Getting a similar result. This is quite problematic...

I also get extra sockets with that command on Ubuntu 18.04 Gnome 3 but I don't get any extra sockets on Debian KDE. @vendethiel what is your operating system?
