perl-IO-Event-0.813-1.fc21 fails t/forked2.t test if the host is under heavy load:
# Looks like you planned 115 tests but ran 111.
print 960: Connection reset by peer
Compilation failed in require at t/forked2.t line 5.
Dubious, test returned 255 (wstat 65280, 0xff00)
Given that this issue is an upstream bug more than it is a packaging issue, I'll be keeping track of it in CPAN's RT. Accordingly, I'm closing this bug with the resolution of UPSTREAM.
Debian provided a patch that fixes the race according to my humble tests. I still encounter this issue occasionally, so I will apply the patch onto Rawhide.
