He might be wanting to see what the child does with the incoming connection
right when it forks. The child may only live long enough to do something
and then exit. I have a daemon that, upon TCP connection, spits out a file
to whatever connects, then exits. If it's a short file, the child is gone
in quite a hurry.

The suggestion to attach after the child exists does help in some
cases. In some others, the child can be modified to wait long enough.

When both of those fail, what did _you_ suggest that works?
