[Zope] Database Adapter - concurrent sessions?

Hi, By adding a Database Adapter I can access my relational database. What I would like to know is if one database adapter supports multiple sessions, e.g. two scripts can query the database at the same time and not sequentially. If yes, is there a way to limit concurrent sessions because in my database (MaxDB) I define a maximum number of user processes - if the number exceeds, I get an error message, this should be prevented by somehow queuing database connections that exceed a defined number.
