from https://medium.com/zendesk-engineering/hunting-for-memory-leaks-in-python-applications-6824d0518774
at the end of `synchronize` task, after: `dv.create()`
I put:

from pympler import muppy, summary
all_objects = muppy.get_objects()
sum1 = summary.summarize(all_objects)
summary.print_(sum1)

and the result was:

Here is how I got the result above:
https://github.com/pulp/pulp_rpm/commit/f3f079010cfe81b7f5cf3ef94c2402b1ccf7d90c

After running the sync test for RHEL 7,
I ran this script:

import linecache
import os
import tracemalloc

snapshots = []

traces = [t for t in os.listdir("/tmp") if t.startswith("tracemalloc-")]
traces = sorted(traces, key=lambda t: int(t.split(".")[-2].split("-")[-1]))

def display_top(snapshot, key_type='lineno'):
    snapshot = snapshot.filter_traces((
        tracemalloc.Filter(False, "<frozen importlib._bootstrap>"),
        tracemalloc.Filter(False, "<unknown>"),
    ))
    top_stats = snapshot.statistics(key_type=key_type, cumulative=True)

    for index, stat in enumerate(top_stats, 1):
        frame = stat.traceback[0]
        # replace "/path/to/module/file.py" with "module/file.py"
        filename = os.sep.join(frame.filename.split(os.sep)[-2:])
        if (stat.size / 1024 / 1024) < 1:
            break
        print("#%s: %s:%s: %.1f KiB"
              % (index, filename, frame.lineno, stat.size / 1024))
        line = linecache.getline(frame.filename, frame.lineno).strip()
        if line:
            print('    %s' % line)

    other = top_stats[index:]
    if other:
        size = sum(stat.size for stat in other)
        print("%s other: %.1f MiB" % (len(other), size / 1024 / 1024))
    total = sum(stat.size for stat in top_stats)
    print("Total allocated size: %.1f MiB" % (total / 1024 / 1024))

print("\nLast Snapshot") 
last_trace = "/tmp/" + traces[-1]
snapshot = tracemalloc.Snapshot.load(last_trace)
display_top(snapshot) 

sometimes the last snapshot is corrupted because it was being saved when proccess got killed
