        src/tests/lib/libc/string: t_memmem.c

Log Message:
map enough space for both the page we write and the guard so that we make
sure we own the guard page before we set its protection to none. This fixes
random SEGVs where the page we set protection to none probably belonged to
the dynamic linker. Reported by gson@
