It does, but it can't stop you from doing things like putting a
database handle in a global during startup and trying to use it later.

That's a different kind of timeout.  I meant you may have a really
slow query that takes too long to read from MySQL, not that the
handles would be stale.

Getting errors right after startup makes it sound more likely that you
are storing the database handles you open during startup and trying to
use them.
