I experienced a similar problem starting with 5.17.6 in pipes
where nobody writes to it anymore..
See https://rt.cpan.org/Ticket/Display.html?id=84292
I fixed it by replacing waitpid on this apparently closed read pipe
with sleep(0)

This definitetly changed with 5.17.6 but I didn't bisect it since I
didn't want to
implement a timeout for my test case.
