extern "C" for the signal handler, please (btw, i think we still need to
check the entire kde codebase for that).

i don't like the mmap_can_jump; using a SA_ONESHOT handler seems cleaner
to me (say hi to sigaction).

there is no point in making mmap_map global; a volatile local variable
is sufficient.
