every pocess forked by dmenu leaves a zombie sh

[pfpulux]

Describe the bug
a application forked via dmenu or a closed terminal, leaves a zombie sh process.

To Reproduce
Steps to reproduce the behavior:

1. open a terminal via dmenu or shortcut
2. close it via exit or Ctrl-D
3. check zombies via top or ps

Expected behavior
A forking sh should be closed after the end of a process.

      ├─runsv───login───bash───startx───xinit─┬─Xorg───{Xorg}
      │                                       └─nimdow─┬─dwm_status.sh───sleep
      │                                                ├─redshift
      │                                                ├─7*[sh]

I think is is a nim problem by startProcess with need to be closed()
