Hello Tony,

Can you tell me where I can find more information about this?

My application is similar to unexec of emacs, tries to save all the
segments in the map file and restore them back, while restoring
currently we assume that if the segment is above sbrk(0) then it needs
to be mmap'ed from the save file else override it.
Looks like If I dont overwrite the RSE backing store fclose on my open
files seem to crash when I restore my program.
