"ld" memory usage

Hi. This is not strictly a GHC question. I observed that "ld" when linking GHC-compiled programs eats 0.5 GB of resident memory. ~3 times more than GHC or Haddock. So if there is not enough free memory "ld" uses virtual memory and works very slowly (practically does not use CPU). I'd like to know, is anyone interested in researching and improving memory usage? Is it "ld" or GHC problem? I found a similar discussion here http://article.gmane.org/gmane.comp.lang.haskell.cafe/66189 but it was too broad and went nowhere. -- Best regards, Roman Beslik.
