I believe unauthorized commands run at or below the TCB where the TSO environment was establish. If you have multiple TSO environments running in a single address space (ATTACH, IKJTSOEV or IKJEFTSR), then commands can run at the same time. I've seen commands in a wait but the other exec's and commands continued to run.
As for authorized commands and the parallel TMP, I've never specifically looked at how it works or what get's delayed. Where can I find information about this?
