That seems highly unlikely, and I cannot reproduce it on my Arch Linux
system, with the following script:

import psutil
import subprocess
import time
import gc
import os

p = psutil.Process(os.getpid())
print(p.memory_info())

while True:
    subprocess.check_output(['true'])
    time.sleep(1)
    gc.collect(), gc.collect(), gc.collect()
    print(p.memory_info())

Output memory usage stays constant after the first two iterations.
