Spans are dropped intermittently

[ThatsNoMoon]

Tracing spans are getting dropped between when they're created and when they should be displayed in Jaeger's query interface. This causes obnoxious warnings: Because parent spans can get dropped, traces can be much harder to interpret.

It's extremely unclear to me why this is happening; nothing I've been able to find on the topic applies to this scenario, as far as I can tell. Seemingly any span could be dropped, and it happens with essentially no load on any Jaeger components, making it unlikely it's a queuing problem.
