Close Python Thread To Prevent Memory Leak

How to I close a Python thread in order to make sure that everything in memory within a thread is cleared from memory? Currently, I have a list of threads that I join in the following manner:

for t in threadlist:
    t.join(5)

These threads were originally created looping over a list of arguments to pass to each thread with myfunc which appends results to a list:

threadlist = []
for r in arglist:
    t = Thread(target=myfunc, args=(r,))
    t.daemon = True
    threadlist.append(t)

When I look at what's in memory with pympler all manner of things in the function called by the thread remain in memory after this executes. I need it to garbage collect as it would if I called myfunc normally without threading.

The objects being deleted were contained within an object function.
Moving them outside of that object function and
into a regular function allowed garbage collecting to occur following delete.
