Comment (by rwbarton):

 The type of behavior you describe is not totally unexpected since when GHC
 compiles multiple modules in a single run, it retains the information read
 from all the interface files it has encountered in case it needs that
 information later. So it's a time/space trade-off, not really a memory
 leak. Of course, it's possible that that interface file information is
 consuming much more space than it needs to. (Or the cause could be
 something else entirely.)
