I think the change should just be backed off - apps should
know best why they mask SIGSEGV, and doing magic behind
app's back like resetting the signal handler is IMHO not right.
So, unless someone thinks different, I'd remove the change by
end of the week and request pullup do 2.0 branch (now 2.0RC1).
