Does Jetpack Override Nonce Timeout Settings?

I have found myself unable to complete Media Cleaner scans whenever a site becomes big enough that Media Cleaner must be left running for more than a day it can never finish the scan without receiving an invalid nonce error.

I tried fixing this by installing the Nonce Extender plugin and setting the nonce timeout to one week. This made no difference during my last attempt at all. Somehow I was still logged out of my site mid-scan and received invalid nonce error after re-authenticating. In the past I’ve remained logged in for days only to receive invalid nonce errors after 12-24 hours.

This leaves me wondering if Jetpack does anything which would override the new nonce setting created by the Nonce Extender plugin.

This is a serios error because I need to migrate some content to new sites but don’t have enough free space on my system unless I am able to delete all images left on the file system of the old site after the migration. To do that deletion I need Media Cleaner to keep running without receiving nonce errors.
