Oh, that's what you meant. So the effort suddenly went from "high" to
"trivial". This is just a flag that is 0 on process start and becomes 1
on the installation of a signal handler. And nothing else.
Honestly, as hacks go, I've seen way worse. The ugly thing is the bug
we're working around. Might be worth a comment, though.
Ciao,
