starting with fanout/pushpin:1.38.0 i'm running into a 5 sec delay/wait before any http headers/response are sent back to the client by pushpin, although the backend responds immediately with 'Grip-Hold'.
logs reveal the same 5 sec delay between [condure] [pushpin::connection] server-conn 0-0-0: request: GET http://localhost:7999/, and [handler] accepting 1 requests
everything works fine with 1.37.0
running on MacOS, Apple Silicon M2
