This has just happened to me as well, and I think the reason is that,
when a download failure happens (500, 502, 504, etc.), the thread doing
the download directly writes to the current error port.

And as we know, ports are not thread-safe in Guile 2.0 and we=E2=80=99re not
doing additional synchronization here, so everything wrecks havoc.

This is another incentive to merge wip-http-pipelining.  I=E2=80=99ll give =
it
another try.

Thanks,
Ludo=E2=80=99.
