Workaround a zombie process created by Open3
with MJIT worker enabled
The problem:
```
$ ruby -ropen3 --jit -e 'Open3.capture2e("cmake") rescue nil;binding.irb'
irb(main)[01:0]> Process.waitall
=> [[10656, #<Process::Status: pid 10656 exit 127>]]
$ ruby -ropen3 -e 'Open3.capture2e("cmake") rescue nil;binding.irb'
irb(main)[01:0]> Process.waitall
=> []
```
Not sure why it's happening yet, but first I'd like to prevent trunk-mjit-wait
from failing like http://ci.rvm.jp/results/trunk-mjit-wait@silicon-docker/2929075.
