Possible races while concurrent additon to the new sessions vector
in a one process and remove from it in an another need to be avoided.
Let the vector be changed in the new session process function only.
Also cli_file_pool element may be freed already at the new session
event arrive timepoint, still causing unexpected cli banner for
noninteracive cli sessions.
