Funny you mention it... :) We were just having this conversation on IRC 
about Nikesh's issues with some Tempest volume tests and a token 
expiration problem.

So, yes, a Glance upload operation makes a series of HTTP calls in the 
course of the upload:

  POST $registry/images <-- Creates the queued image record
  ...  upload of chunked body of HTTP request to backend like Swift ..
  PUT $registry/images/<IMAGE_ID> <-- update image status and checksum

So, what seems to be happening here is that the PUT call at the end of 
uploading the snapshot is using the same token that was created in the 
keystone client of the tempest test case during the test classes' 
setUpClass() method, and the test class ends up running for >1 hour, and 
by the time the PUT call is reached, the token has expired.
