Maybe there is a simple solution to this. Add END{ system qq(tasklist /v /fo LIST /fi "PID eq $$") } to your child code and you'll have some useful info. If you want the whole mess of infos add instead END{ system qq(wmic  PROCESS where "processid=$$" get * /FORMAT:LIST) }
#cat child.pl
use strict;
use warnings;

print "I'm the child with PID $$\n";
sleep 3;
print "Exit now.." and exit 0;
#END{ system qq(tasklist /v /fo LIST /fi "PID eq $$") }
END{ system qq(wmic  PROCESS where "processid=$$" get * /FORMAT:LIST) 
+}


# call it from a oneliner
perl -e "system ($^X, qq(child.pl))"
I'm the child with PID 298184
Exit now..
