No, I mean blocking is not error.
One method to find it, run gdb or strace and see where the
process stopped, or which syscall was last. But I believe that

Easier said than done as there's no signal the child sends to say
"OK, I'm waiting now".
You can use expect to do this, if you know what the output of the
child will be just before it's waiting for IO.
This is the D lib I've written to do this:

It's not wonderful or anything, but it works :)
