If possible, it would be nice to hold off on merging this until #42885 is merged.

[StefanKarpinski]

Well, I guess the good news is that the CI failures don't appear to be related to Downloads? Can hold off for whatever or re-bump afterwards. Whatever's convenient.

[DilumAluthge]

I merged #42885 and triggered a new bump. Now the Pkg test suite is going to run on this bump PR, so we can see whether or not it breaks the Pkg tests.

[StefanKarpinski]

FreeBSD failure is some LBT issue. Presumably unrelated.

[DilumAluthge]

Yeah, I think the tester_freebsd64 failure is unrelated. I'll open an issue.

It looks like the Pkg test suite passed (on Buildkite), which is good news.

If all CI jobs (other than tester_freebsd64) pass, I think that this is good to merge.

[DilumAluthge]

Yeah, I think the tester_freebsd64 failure is unrelated. I'll open an issue.

#42944

[DilumAluthge]

The tester_win64 failures are not due to this PR. See #42950

[StefanKarpinski]

Fingers crossed that this one sticks and we finally have a threadsafe Downloads.
