 No, if it's never going to work replace it with a stub that returns -1
 with errno EOPNOTSUPP, one in the kernel and one in libc. Then remove
 the libc stub when the mythical version bump happens.
 
 exect is historical, but I don't think that means we need to keep it;
 any vintage debugger that someone might dig up in a basement will need
 a lot of porting work anyway, and it's not like there have ever been a
 lot of unix debuggers around.
