I can confirm that I wasn't able to reproduce the errors with the attached (and
the sleep() removed) running the tests over and over in a loop on Linux and
OpenBSD.  Moreover, I was also unable to reproduce the error when only ignoring
EPIPE.  When only ignoring ECONNRESET it worked intermittently on OpenBSD (but
all the time on Linux as expected).

Off the cuff I can't think of a case where it would lead to adverse effects
*during startup*.
