finding .o

[S.D.Mechveliani]

ghc-5.00.1 -interactive  (binary, linux, i386-unknown)

forgets sometimes of existing  Foo.o  module to load and loads 
instead the interpreted code.
A strange effect. 
Compiled and loaded is a single module  Foo.hs  in the current 
directory.
In such cases I compile  Foo.hs  once more, rerun  ghci, 
and then it finds  Foo.o.
How to trace this down if the effect is not always reproducible?
