We would like to limit the number of concurrent executing actions on a Target Powershell session. With this we can use Powershell target connectors more easily with systems like SAP, Exchange, Skype and more. This because we limit the number of actions we therefore limit the number of active sessions to the external target system so we support all target systems which have a limit on the active open sessions.
In some cases this could help with overflow a system with api calls in x period because the amount of action overtime we can finish will be lower but this depends on the target system limitations. Becarefull that this isn't a solution for this last case (limited amount of api calls in a period) in some situations.
