Subject: If we get to sighandler by mistake (no perl handler set) then
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=727405f80c5904bbe9e96e63570ee4516290a454;p=p5sagit%2Fp5-mst-13.2.git

If we get to sighandler by mistake (no perl handler set) then
warn() and exit() rather than die() - should never happen
but if it does context needed to die is likely to be trashed
as well.
