Powerful  intel-686  machine, much memory:

cpu family      : 6
model           : 6
model name      : AMD Athlon(TM) MP 2000+
stepping        : 2
cpu MHz         : 1666.742

Maybe,  ghc-6.2.1  has a memory leak ...

Another reason may be that my GHC competes with other users programs,
and they have higher priority (I do not know).

Now, I restarted       > cd myfptools
                       > make all
It advanced up to
  ../../ghc/compiler/ghc-inplace  -H16m -O  ...
                             Text/ParserCombinators/Parsec/Token.hs 
  ...
and continues. 
Probably, this means that the compiler (and its PrimOp) has compiled,
and now the `make' is dealing with the library?
