I see the same behaviour as Andreas for this test case. I took a brief
look, and it seems that on my system, the hack does in fact work and
trigger recompilation of Imports/Nat (although not of the other two
modules in the expected output?), but GHC sends the progress info to
stderr and MAlonzo sends GHC stderr to a dead pipe, so it is not
output. It appears that this was changed in GHC 7, which now sends the
output to stdout, so I suspect the problem is a GHC version thing. I'm
still running GHC 6, so I suspect Andreas as well and Nils not?

Anyway, perhaps an idea for a fix: maybe there is a way to pass "-v0"
as ghc option just for this test case? Nils, maybe you know by heart
how to do this from GHCi top?
