OSToken.cpp(600): Token integrity check failed

[glance-]

I use softhsm via p11-kit remote tunneled over ssh, to provide developers the ability to sign things without having access to the actual key.

This mostly works great, but now and again, softhsm fails and logs:

OSToken.cpp(600): Token integrity check failed
ObjectStore.cpp(74): Failed to open token <uuid>

This is probably due to parallel access to the same object, because it mostly happens when running make with a lot of parallel jobs and signing multiple things simultaneously. The higher parallelism, the more likely it happens.
