Note that the description is about an error within the parent process.
In the case snipped above it is the parent that exits early, not the child.
This first paragraph describes two scenarios, (a) error in parent, and (b)
error in child. I think it is good information to keep descriptions of
both scenarios.

The proposed addition could be used to expand the description of the scenario
when an error occurs in the child. In this case please consider changing "wait
pipe message from child" to "wait for the pipe message from the child", and
"proceeed" to "proceed".
