Comment(by mornfall):

 As for solution 1, is there a way to use C finalizers without having C
 code (and C symbols)? The workaround is what we already did (we copied the
 mmap dependency from hashed-storage into darcs.cabal), but I don't think
 it fixed all version mixups (see also
 http://irclog.perlgeek.de/darcs/2010-06-14#i_2434140). Would solution 2
 involve manual renaming of all C symbols in each version? (That is quite
 inconvenient and error-prone...) The C functions are supposed to be
 private, so maybe a hiding solution would work better? Is that doable with
 current Cabal?
