you mean why the "duplicating-tab-fixes-problem" ?
because requesting a cached object for the second time doesn't trigger the 
same execution path.

instead of being fetched asynchronously, the script object will be immediately 
available from cache, so synchronously executed, so all the queuing logic this 
patch is about is avoided.

anyway, as I said I just forgot a bit where I remove the lock and consume the 
data - I can't commit that bit at the moment because of other changes in my 
tree, so I disabled the patch in trunk in the meantime.

I should reenable in a few hours.
