cef1f3c7ee withReactiveDomain now acts as a promise domain 
Without this change, async handlers won't return any
value for getDefaultReactiveDomain().

    library(shiny)
    library(promises)

    ui <- fluidPage(
      p("This app tests if async handlers have reactive domains. You'll get a yes/no answer below."),
      h3(
        "Does it work?",
        textOutput("answer", inline = TRUE)
      )
    )

    server <- function(input, output, session) {
      output$answer <- renderText({
        promise_resolve(TRUE) %...>% {
          if (!is.null(getDefaultReactiveDomain()))
            "Yes!"
          else
            "No :("
        }
      })
    }

    shinyApp(ui, server)

132f90f45b Support promise domain wrapSync; fix renderPrint visibility 
Also introduce promise_chain and hybrid_chain, for assembling chains of
operations without involving magrittr-style operators

2602dc15b0 Changes to flush cycle to support async 
- Moved (in|de)crementBusyCount calls out of Context and into Observer
- decrementBusyCount is (effectively) deferred for async observers until
  the async operation is complete
- invalidateLater didn't force(session), almost certainly was buggy
- invalidateLater, reactiveTimer, and manageInputs all now use a new
  session$cycleStartAction, which delays their effect until observers
  (including async ones) are done executing

aff3ac0bb3 Add onStop function (#1770) 
* NEWS item

* added `onStop` arg to `shinyApp()` (and renamed our internal `onEnd` - which is what was calling `on.exit()` already - to `onStop` as well)

* added onStop() function

* add entry for documentation

* make it work for all possible app structures (interactive, saved as app.R, saved as ui.R and server.R)

* fix #1772: make sure `onStart` works in all scenarios

* update NEWS

* improved wording

* more wording

* and more wording

* don't stop execution if a `onStop` callback function results in an error

* remove "(all sessions have been disconnected)" because it's misleading

* add @seealso documentation

* shamefully forgot to Cmd Shift D

* change code place

* Code review feedback

* onStop: use session argument instead of scope
