    33This nesting is basically the same as overlapping (with the only difference is that nesting is a complete overlapping, i.e. when the file is entirely mapped twice or more). And we already have a ticket for the overlapping problem, https://github.com/bitwiseworks/libcx/issues/29. This is where it has to be fixed.

    5 Note that the old MMAP implementations is free of this problem since it supports a trivial approach where each mmap call results into a new memory region so nesting/overlapping is given for free there (but this approach leads to many other problems like different mappings going out of sync etc).
