Using the GHC heap profiler

[Tim Docker]

My question on the ghc heap profiler on stack overflow:

http://stackoverflow.com/questions/5306717/how-should-i-interpret-the-output-of-the-ghc-heap-profiler

remains unanswered :-( Perhaps that's not the best forum. Is there 
someone here prepared to explain how the memory usage in the heap 
profiler relates to the  "Live Bytes" count shown in the garbage 
collection statistics?

Many thanks,

Tim
