No luck. The tests passed locally a hundred times, but two of them 
failed on the buildd 
(https://buildd.debian.org/status/fetch.php?pkg=libio-socket-ssl-perl&arch=all&ver=2.060-1&stamp=1537167776&raw=0).

Wstat: 13 seems like the process was killed by SIGPIPE :(

I can reproduce this looping over the two tests for a thousand times.

I'd patch the two failing tests to ignore SIGPIPE, but I wonder if it 
would be even better to patch all the tests like that, to avoid the 
whack-a-mole game with the buildds.
