[imp] DB Connection Handle Consumption

[Chuck Hagenbuch]

Quoting "Sexton, George" <gsexton@mhsoftware.com>:

> Connection object.

This all works for servlets. The PHP architecture is different. Like I 
said, there's a _lot_ on this in the archives; the short summary is that 
you end up having at least 1 connection per apache child per user - and 
that's not workable.

> An alternate approach would be to save the Connection object on the

> probably would not scale as well as the other, more complicated approach 
> since sessions can be arbitrarily long.

Also, you can't toss open sockets (for example) into a PHP session.
