Yep, it'd have been a lot of luck, being your hang related to
different operations from those touched by this fix. Maybe
time-before-failure stretched because your system suffered from the
illness cured by this fix too.

BTW, if you didn't run out of patience with this permanent issue yet,
I was thinking of two o three changes to retry to trigger your failure
reliably. In case of success, I could restart racking my brains from
there.

Thanks,
