sftp backend test weirdness #61
Description
It's not visible on github actions CI (we skip the sftp tests there), but the sftp backend / store test sometimes behaves weird:
Especially the test_scalability_big_values and the test_scalability_size seem to trigger test teardown errors (the .destroy is then failing, not cleaning up the sftp server and then causing more errors in the following tests).
When using pytest -v -rs -k "not big_values and not scalability_size", all works fine.
I am seeing this on macOS 15 with the default macOS sftp server on localhost.
Update: when using a remote sftp server (debian linux based, OpenSSH), it works.
