I get:

    failed in thread#1, var is local-4
    failed in thread#2, var is local-4
    failed in thread#3, var is local-4
    failed in thread#0, var is local-4
    succeeded in thread#4, var is let

which indeed is quite wrong, since the thread let-binds `doomsday` to
"let" and then doesn't mutate it anywhere.

Sounds like a bug in the context switch code.
