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.

Written by the indexing model from the issue text.

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).
