There is no documented invalid value. It's a opaque handle we get from
libc and different versions of libc interpret the value differently.
Sometimes it's a pointer, sometimes it is not and we have no idea what
it is until we try to pass it to the timer functions.

So choosing safe enough safe value and handling SIGSEGV is probably the
best we can do.
