My ptrace patches are only needed if the ptrace poke to 0x11115555 is still in
the code (this poke turned on interrupts for uninitialized trap addresses which
caused the unhandled exception crash).  If the 0x11115555 poke is removed (most
likely removing workarounds and support for earlier linux versions) the trap
addresses should not need to be iniitialized with 0s (an address which won't be
hit)
