Description

Look at the html page I provide. Test on IE7.

If I use jquery-1.0.2:

If I click on "create" and then on "destroy" several times, it takes in my computer around 280ms to do "create", and around 400ms to "destroy".

If I use jquery-1.1.3.1:

The first time I click on "create" it takes around 1500ms. I click on "destroy" and then click again on "create", now it takes 2300ms. I click on "destroy" and click "create" again and this time I get a popup from IE7 asking me if I want to stop the script.

The only difference is the version of jquery that I use.

There's still some fluctuation, which is normal, but I appear to have solved this problem in another commit [2783] that I fixed (related to global events, bug #1463).
