Ready handlers are added to the readyList Array, which I'm sure is confidential, so I don't think you can directly influence it.
You might want to add code to readyList , but put it in setTimeout() so that it readyList little. Hope everyone else will be done first.
However, upgrading jQuery may cause problems. For example, there may be differences in the implementation of jQuery.cache , which stores event handlers and other data.
So, if jQuery.cache was populated with one version, it may not be compatible with another.
