I finally got an answer[1] on this -- believe it or not this is actually _expected behaviour_ for Korn shell *and any of its derivates* (of which /usr/xpg4/bin/sh is one as it is based on ksh88). So I guess we should trap SIGTERM and process it accordingly to indicate the test failed? Or do signal traps propagate down to subshells making this impossible?
