disconnect() is all but destroying the working bits underlying the 
Connection object, on the theory that you're not going to use it again. 
  It wouldn't be hard to change DBDriver::connect() to rebuild these 
things (mysql_init(), etc.) if it sees that they've been wiped out by a 
disconnect() call.  Patches thoughtfully considered.

Alternately, you can do as most people seem to do, which is destroy the 
Connection object and create a new one.  Same effect, while avoiding 
this limitation.
