It seems that mate-menu never reaps it's child processes after they terminate, causing them to turn into zombies.
Steps to reproduce the bug :
Open 'n' applications from mate-menu and watch the zombie count (in top) pile up as you close the windows one by one.
Here's the output of ps -el | grep "defunct" after opening 3 applications and then closing them one by one :
0 Z 1000 10932 10899 1 80 0 - 0 - ? 00:00:00 atril <defunct>0 Z 1000 10966 10899 0 80 0 - 0 - ? 00:00:00 ghex <defunct>0 Z 1000 10970 10899 1 80 0 - 0 - ? 00:00:00 mate-calc <defunct>
where 10899 is the pid of mate-menu.
System Details
Distribution=Arch Linux
pkgver=18.04.3

I did try ignoring SIGCHLD but doing so probably interferes with some library initializations and breaks the Windows (Super) Key's functionality (hide/show menu). Option 2 (double fork method) seems to be working fine on my system (for now).
