Description
the init/exit sequence is not cleaning up all resources. this short sequence shows the case:
from sane import init, get_devices, exit as deinit
for _ in range(99):
init()
d = get_devices()
with open("/etc/hosts") as f:
print(f.fileno())
deinit()
as you can see the fd will increase (by 78 in my case).

Research direction
Start by running the supplied loop and tracing the init(), get_devices(), and deinit() entry points involved in SANE resource cleanup. Compare file-descriptor counts across repeated iterations; done means the count remains stable after deinit() instead of increasing.
