Nevermind, I found my mistake.
I was capturing the handle inside a lambda expression. Usually it works
because most of my "handles" are pointers to persistent values, this one
was not. At some point it was just too easy to do [handle]() { ... code ...
} and it kinda worked "sometimes". Sloppy code.
Anyway, Ben, thanks for your attention to this.
