That's true. Scratch this patch - it's too painful on ia64 anyway, and it
doesn't nest correctly in the first place. We'd need to save off the
"restarted system call number" in user space too to get proper nesting,
just saving the arguments isn't enough.
So we're just going to have to live with the fact that restarting doesn't
nest. I think the gdb example by Daniel was interesting, but perhaps not
all that important ;)
