Description
Consider the following code fragment:
from saxonche import PySaxonProcessor import psutil
count = 0 prev = (mi := psutil.Process().memory_info)().rss
for _ in range(100): with PySaxonProcessor(license=False): pass if (count := count + 1) % 10 == 0: m = mi().rss print(f"{m - prev:,}") prev = m
It can be observed that memory usage increases over time. The exit functionality of the PySaxonProcessor class is not "cleaning up" as robustly as it should.
Python 3.12.2 saxonche 12.4.2 macOS 14.4.1 M2

Apologies for incorrect code formatting in initial submission:
from saxonche import PySaxonProcessor
import psutil
count = 0
prev = (mi := psutil.Process().memory_info)().rss
for _ in range(100):
with PySaxonProcessor(license=False):
pass
if (count := count + 1) % 10 == 0:
m = mi().rss
print(f"{m - prev:,}")
prev = m
