Figure out why req$ arguments linger between requests.

I think it's a bug in httpuv. Come up with a workaround and report it if so.

With a simple httpuv listener, setting the HTTP_CONNECTION to "close" did the trick. By default the connection is set to "Keep-Alive".

req$HTTP_CONNECTION <- 'close'

Is there plans to fix this issue in future?

We "solved" this using the same approach you suggested above in https://github.com/trestletech/plumber/blob/f292ef032aa58ae2871edbd9be60e720698dc5b8/R/response.R#L25-L27 which is how I closed the ticket.

But the underlying issue in httpuv is still open and is being tracked here: rstudio/httpuv#49
