+Subject: [PATCH] workaround for race condition in t/01-base.t [RT #113449]
+
+It's possible that the TERM signal handler is not yet installed
+in some workers when the last worker runs and sends the final
+TERM signal to the parent. The effect is that the number
+stored in the temporary file is not as expected, as in this report:
+http://www.cpantesters.org/cpan/report/86348529
+
+This failure seems to occur quite frequently on (virtual?) FreeBSD
+systems.
