*I* sure wish we could. From the standpoint of trying to trace system calls,
it's a big stinking black hole. All of the other syscalls (I think) have
pretty well defined semantics in terms of what they do to a process' memory
space, but the semantics of ioctl are "may read or write any memory
whatsoever, and if you want to know what, well, it sucks to be you".

Even NT does this better, if I'm interpreting this correctly:
