Problem

We have started to see following network errors:

  warning: spurious network error (3 tries remaining): [28] Timeout was reached (Operation too slow. Less than 10 bytes/sec transferred the last 30 seconds)

as reported here: quinn-rs/quinn#2218

Note that it's running Solaris under QEMU in Linux. I guess that there might have been some changes to QEMU and/or Linux underneeth which enabled these problems. Unfortunatelly main victim seems to be Solaris.

I have come with following workaround. But the cost seems to be longer times...
