I am using gdb on a program with efence. If gdb caches efences
segv for a bad access and then I try to do something like

sizeof(array) == 22
set array[24] = 1;

The machine will hang. SysRq can still reboot it but nothing else
seems to work. This is one SMP boxes. I can only guess there is some
mishandling with mprotect?
