Comment (by darkdragon):

 I feel like I'm back in C/C++.

 I'm not seeing how the patch does anything that shouldn't already be
 available. I'm not sure that the patch fixes anything. If $wpdb isn't
 available then {{{global $wpdb}}} doesn't do anything except declare an
 variable that was nonexistent. If it did exist, then global $wpdb; should
 just acknowledge that the variable existed in global scope anyway.

 That doesn't seem to be a solution and if it is, then you just turned
 everything I think I know upside down and I should stop programming
 completely because I don't know anything.

 It seems unrelated, what is the execution flow? You said it includes your
 plugin twice, which it should not do and even if it does, you only execute
 the init once, so it should blow up on your function and not on the
 require_once().

 In the case that it did execute the function twice, then it should still
 only include the file in require_once() one time, as would be the case
 with require_once(). If not, then you have a PHP bug with require_once().


 Both the solution and the problem seem completely mind boggling and my
 brain is about to implode. Can you further explain, so that down is not up
 and reality is real again?
