wont be stripped in a middle of code.

214b8a6a27 restore: Update memory size needed for restorer code 
Since VMA areas are allocated with page granularity
better to reflect this in mmap request. This would
allow the restorer to do munmap on page boundaries.

65e9402d47 restore: Fix pipes restore if both pipe ends are used by former process 
In case if the former process used both pipe ends we fall
into endless loop since the 'users' never reaches 1. So
to resolve this during the pipe collectioning we check if
both pipe ends were used by a former process and if so --
we connect first pipe end immediately in create_pipe and
connect the rest via  attach_pipe.
