Sounds okay.

No. First of all, what you describe would only happen if a session was 
opened/closed multiple times on the same page. $_connected does not 
persist across requests, just like any other PHP variable. Second, even 
in that case, the _pconnect functions don't open a "new connection" if 
there's already a persistent one - they return the existing persistent 
connection. That's the whole way persistent connections work.
