Additionally, since the demand loaded environment is a separate evaluation environment, all data will necessarily be duplicated (in theory sharing of initialized data with copy on write is possible, but in practice it's a lot of work and demand loading overhead for (for most C/C++ programs at least; ghc initialized data might differ) very little practical gain). -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
