This change fixes an oversight in the Connect_Socket variant that includes
a timeout check. The connection is initiated asynchronously, and a select(2)
call is performed to wait for it to complete, with a timeout. When that call
returns however, the connection is not always succsefully established.
This patch adds a clarifying message info when subtype conformance fails, due
to a missing null exclusion indicatar in a formal that must match a controlling
