unable to repro in 3K runs (win 10, I don't have a win 2008). Better wait to see if it occurs again.

addaleax added a commit to addaleax/node that referenced this issue Feb 3, 2019
The Windows ETW code is not written to be compatible with multi-threading,
and in particular it relies on global state like a single static
`uv_async_t`. Adding that to multiple threads would corrupt the
corresponding loops' handle queues.

This addresses the flakiness of at least `test-worker-exit-code` and
very likely other flaky tests that relate to Worker threads on Windows as well.
