fatal: ::read(fd, buffer, maxBytes): Connection reset by peer

[ohwgiles]

Beginning a new issue for the problem reported by @jbglaw and discussed at #146 after the issue was initially closed.

Under some circumstances, Laminar may catch a fatal exception and exit with this output: fatal: ::read(fd, buffer, maxBytes): Connection reset by peer.

The original error causing the exception comes from here, when read returns -1 with errno == ECONNRESET.

In 0281030 I made the error non-fatal, but then the http server stops accepting new connections.

The underlying behavior of the kj library is being investigated here.

In the meantime, this issue can be addressed in laminar by catching this exception and restarting the http server.

Hey @ohwgiles, thank you for this fix! I have continuous problems with this issue for quite a while.

Do you maybe plan to do a bug fix release soon? That would be awesome!

I maintain laminar in nixos and observe about on laminar crash per day on my personal server. So I would prefer to not expose our users to this problem for much longer. If you tell me that it will be a while until the next release, I will consider applying some patches downstream.

Thanks for maintaining the nixos package! I intend to have a release out within a week or so.
