Shutdown crash on Windows: lib\isc\netmgr\netmgr.c:275: INSIST(r == 0) failed
First observed in a scheduled pipeline run for 1dd265df:
https://gitlab.isc.org/isc-projects/bind9/-/jobs/1014592
I am only making the issue confidential out of abundance of caution as
the crash seems to be caused by a call to uv_loop_close()
returning a non-zero value.
