Subject: Top was catching sigterm (and fumbling sigint) so it could reset the terminal
X-Git-Tag: 1_2_0~69

Top was catching sigterm (and fumbling sigint) so it could reset the terminal
type on the way out, but the signal handler didn't exit.  Plus it did
unnecessary things with sigaction.  This code is overgrown and needs a serious
weed-whacking...
