I was waiting for the next freeze while in Helm. It happened, but while
reading mails in Gnus. So, a different context -- though, I did not change
anything of the rest: same Emacs, same config, same Helm version, same Gnus
version, etc.

Hence, this time, there was no es.exe process involved in the problem.

Here the new backtrace:

I tried the "finish dance" as you call it, but it never answered. I was forced
to kill Emacs by other means (here, DEL in the process explorer from
SysInternals).
