Detailed Description

This class represents a connection stored in the pool. It may be in different states:

• available and reuseable for this user (open=0, tx=null)
• reusable for the same transaction, not already committed (open=?, tx!=null)
• still open, but not involved in a Tx (open=1, tx=null) These 2 cases must be considered: close after commit, commit after close. We cannot suppose what shema the user will use and we must handle both correctly.
