Mikhail's original question was about loading interface files for entire
packages with mmap.
As a wild thought experiment, if GHC had a saved-heaps capability, I
believe that would avoid the Unique issues with mmap'ing individual data
structures that Simon mentioned. How about if each whole-package interface
were then a GHC saved heap that, when booted, would become an "interface"
server that would communicate with, and be shared by, other GHC build
