Still a bit unclear on whether parts of this are intended or just
emergent behavior, as noted in

FWIW also the discussion as of https://public-inbox.org/git/87lg0x9voz.fsf@xxxxxxxxxxxxxxxxxxx/

I had the feedback of effectively "why retry if we can just make the SID
unique enough" in
https://public-inbox.org/git/874l7rcqk9.fsf@xxxxxxxxxxxxxxxxxxx/ on
March 25th.

You seemed to think so, but after Jeff Hostetler made the SID more
unique (AFAICT "actually unique" in practice) in the parallel in-flight

I think it's fine to merge js/trace2-to-directory down as it is, but do
you/Josh think that retry logic needs to stay with that sort of SID?
