> Log:
> It appears that pausing requests for a Context during reload was relying on
> the mapper not being cleaned up correctly. The Lifecycle refactoring cleaned
> up the mapper registrations and broke the handling of paused requests. This
> commit restores that functionality and extends it. The key changes are:
> - Contexts are no longer from the mapper if they are stopped while they are
> paused
> - The CoyoteAdapter pauses for 1s if a request is mapped to a paused Context
> and then tries to re-map it. This replaces the reloading handling in the
> StandardContextValve
> - The reload handling has been removed from the StandardContextValve
> - Editing a watched resource now triggers a reload (that pauses requests
> received during the reload) rather than a stop/start which will return 404s
> for requests received while the context is stopping and starting
>
> As with previous iterations of this feature it is impossible to completely
> eliminate the chances of a 404 without a fair amount of locking that would
> slow things down unnecessarily in production.

I think it also needs "version = null"; here.
The version variable is modified in the mapping loop.
