 * avoid weird interactions bewteen the MC and the application;

 * use optimisation for the whole MC process;

 * avoid the stack-cleaner for the whole MC process.

The functions MC_process_read and MC_process_write are defined to
abstract memory access:

 * when the target process is the current processs, they call

 * otherwise they call `read` or `write` on `/proc/$pid/mem` (on newer
   kernels, `process_vm_readv` and `process_vm_writev`) could be used.

A lot of bits are missing such as:

 * access to `std_heap` is currently not process-aware (the current
   process is used);

 * access to SIMIX layer from MC;

 * communcation/synchronisation between the processes;

 * …


 * for the per-page/chunked snapshot the current implementation uses
   an extra copy (and one syscall per page), we can do better than
