As part of PM-3221 we're reviewing certain shared variables to see if we can achieve the same concurrent access with mechanisms other than shared variables and memory barriers.
In this ticket we'll review the usage of shared variable WT_CONN->session_cnt and how it is used to allow concurrent access to sessions in the WT_CONN->sessions array.
It's possible an atomic session_cnt would be sufficient we should consider that option.
