apparent memory leak in --make mode (compiling base library during building ghc)
I've noticed that my memory usage slowly goes up and up, and not down until the ghc-inplace ... --make ... -O ...
of all base at once finishes. There is not such a memory reduction between the individual file compilations within the --make. By the end it's using around 200-400 MB of memory. Compiling files individually doesn't seem to have such a large memory occupancy. I could probably gather more details/sureness if it would be useful... for now I am just noting this effect. (I think when I built jhc, which is built using ghc --make, it also ended up using large amounts of memory.) Is the high memory usage just a symptom of importing lots of modules even with separate invocations of ghc, or is ghc remembering more than it needs to in --make mode, or does remembering all the .hi contents at once, of all modules that have been compiled and will be needed sometime in future compilation, take that much memory?
