Sure, and I wrote it in that PR: zombie is the information for the wait,
no zombie - no infromation.

But are there programs which call signal(SIGCHLD, SIG_IGN) and then trying
to wait()? I supposed that there are no such: suggested behaviour of signal()
is the standard for a lot of systems. Yes, I know that most of them are SysV.
But do we have such non-portable BSD-only products trying to use
signal(SIGCHLD, SIG_IGN)/wait()?

I may be wrong of course, but would anybody points me out the product that will
be broken after such changes? Thanks in advance!
