The "kill -SIGNAME" syntax was added in perl 5.18.0.

... For the sake of clarity, I need to retract my claim in "Environment" section about perl being threaded. As "perl -v" states, that is not the case (but being threaded has no bearing on the error per SREZIC's note & my own testing.) Thanks SREZIC. - parv --

Thanks again. Indeed, above code works just dandy in ... # perl -v This is perl 5, version 18, subversion 4 (v5.18.4) built for \ i386-freebsd-thread-multi-64int Copyright 1987-2013, Larry Wall ... # perl -MTime::Limit=-group,-verbose,2 \ -E 'say scalar localtime() while 1' 2>&1 | uniq Thu Jan 8 11:35:08 2015 Thu Jan 8 11:35:09 2015 Thu Jan 8 11:35:10 2015 Thu Jan 8 11:35:1Process 2176 timed out! at -e line 0.
