Update TODO.ptrace

Mark exect(3) for removal, there is no use-case for it. exec() is already
monitored and emits SIGTRAP when traced.

Accessor for siginfo_t is not case for PT_IO -- it's not reading/writing
process space of other process, but shared kernel space.

    PTRACE_O_TRACECLONE, PTRACE_O_TRACEEXIT from Linux

 and of course: fix as many bugs as possible.
