If a user performs a blocking task in decorator chains or services, they have to 1) submit a task to a blocking task executor,
2) pass the result to a CompletableFuture and 3) wrap the CompletableFuture with HttpResponse.from().

sb.serviceUnder("/web", service.decorate((delegate, ctx, req) -> {
    CompletableFuture<HttpResponse> future = new CompletableFuture<>();
    ctx.bl

Preferable with scalatest/scalacheck

Probably requires #2
