    [heap,snapshot] Replace first page size from snapshots with page trimming · ed8791ea
    mlippautz authored
    Replace first page size in the snapshots with a heap logic that trims pages
    after deserialization. The snapshot provided page sizes was just an
    approximation, while the heap knows exactly where to trim.
    
    Furthermore, trim the pages directly after deserialization, leaving no wiggle
    room for further objects. This avoids pollution of the immortal immovable pages
    with regular objects, e.g. Contexts. The downside is that we potentially require
    expanding the space with a new page.
