How interesting. :-)

That suggests processing the headers in Cocoa would take almost 4x  
what it takes on GNUstep (all other things being equal),
and so a precompiled header would indeed have a much larger effect on  
an Apple build.

That would explain why Apple developers are so keen on it.  I couldn't  
really figure out why they are so keen on precompiled headers
because when I tried them on GNUstep it was so hard to get any big  
performance speedups out of them. ;-)
