Indirection vs. in-place update of closures

Hi,

Is there any data available on how often, in GHC-generated code,  
closures are being updated in-place as opposed to and in comparison  
with being replaced by indirections to their results?

How is it decided whether an in-place or an indirecting update is  
performed?

Thanks,

   Stefan
