If Linus eats my siginfo kernel patch (it clashes with your NSIGCHLD,
hopefully Linus will want to resolve that failed hunk), then hopefully
all should be ready, apart from a few missing kernel siginfo generation points.
Now the whole thing has to be heavily tested with 2.3 and 2.2 kernels.

Oopsie, you're right, should be there as well.
On the other side, the comments are pretty misleading in SIGCHLD and SIGPOLL
cases. Those structure layouts are for child deatch signal (which can be any
signal) and you can pass si_band/si_fd with signals other than SIGPOLL as
well.
