The C language stack growth does an implicit mremap. If you want absolute
guarantees and run close to the edge you MUST mmap your stack for the
largest size you think you will need. For typical stack usage is does

not matter much but it's a corner case if you really really care
In mode 2 the MAP_NORESERVE flag is ignored.
