Well this is interesting. So what you are saying is that if your haskell
application requires a peek memory utilisation of (for example) 1GB, after
the memory intesive computation has completed and the GC has run (assuming
all references have been dropped) the GHC RTS will retain the 1GB allocated
to the process. Does this occur on both windows and posix platforms, does
anyone know ? If so then this is a real issue. It would be reasonable to
expect that the RTS release resources to the OS when not explicitly
required.

Hello FFT,

I've heard it's hard to contain a long-running Haskell application in
a finite amount of memory
not exactly. you may alloc fixed pool of memory to application (say, 1gb)
if you know that it never need more memory. but as far as you don't do
it, memory usage grows with each major GC. ghc just don't provide
any way to return memory to OS (there is a ticket on it, you can add
yourself to CC list to vote for its resolution)
