IBM i test failures (`read ECONNRESET`)

Starting with yesterday's daily build, node-test-commit-ibmi is seeing several test failures with Error: read ECONNRESET).

Earlier builds (e.g. https://ci.nodejs.org/job/node-test-commit-ibmi/466/) are passing -- the source change between the last passing build and the failing builds is https://github.com/nodejs/node/commit/c61870c376e2f5b0dbaa939972c46745e21cdbdd (the libuv 1.42.0 update). For the record, the libuv builds (libuv-test-commit-ibmi and libuv-test-commit-ibmi-cmake) have been passing.

Both the failing builds were on test-iinthecloud-ibmi73-ppc64_be-1. I've started a new build (in progress) on test-iinthecloud-ibmi73-ppc64_be-2 to check whether it's host specific: https://ci.nodejs.org/job/node-test-commit-ibmi/469/nodes=ibmi73-ppc64/

まず、成功している IBM i ビルド 466 と失敗しているビルド 467 および 468 を比較し、次にコミット c61870c376e2f5b0dbaa939972c46745e21cdbdd（libuv 1.42.0 への更新）を調査します。両方の IBM i ホストで、記載されている並列 HTTP/TLS テストと pummel/test-regress-GH-892.js を再実行し、ビルド 469 を使って失敗がホスト固有かどうかを確認します。回帰の原因が説明され、影響を受けた IBM i テストが再びパスすれば完了です。
