I have seen in the PKCS#11 spec that "parallel sessions" are not supported
"in Cryptoki Version 2.01 and up, no token supports parallel sessions"
but I can also see that a token may have multiple sessions open with the same token because ulMaxSessionCount is defined as (the)
"maximum number of sessions that can be opened with the token at one time by a single application"
What is meant by "parallel session" if not multiple sessions on the same token?
