Comment(by mitar):
OK. It took me half of a day but I managed to reduce this. I managed to
remove all special dependencies and I use only
[http://hackage.haskell.org/package/Etage Etage] now.
It seems the problem is connected with that I fork two threads which I
force to be on the same OS thread (with `forkOnIO`) and then run with
`-N2` parameter. I am attaching a program.
I tested it on Mac OS X too and the same thing happens.
