Decompression escape hatch for ELF can require a new page.
...
If not enough room on last page of .text, and ElfXX_Ehdr not PF_X,
then the escape hatch must use a new page.

i386: new stub strategy to avoid problems with early mmap layout
...
The stub occupies the same region that execve() would create
for the original progam. The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.
