I attached some code that should be capable of doing so.

We can use the following commands to do so:
gcore -o /tmp/xxxx $PID
cat /tmp/xxxx.$PID | strings | grep yyy

and use a characteristic string for yyy, so we can see if that string
was really removed from memory.

But that would not be a simple unit test.
