Don't worry, that feature of Warp is completely separate, and will
definitely be staying.

By the way, I've just finished a cleanup of the Warp API: the idea is
to provide three run functions only:

* run, same as now, only allows customizing the port
* runSettings allows configuring all settings (for now, port,
exception handler and timeout)
* runSettingsSocket allows you to provide both the Settings and the
socket to be listened on

I think these changes make the names simpler (no more
serveConnections) and remove redundant functions (runEx). If everyone
interested can take a look at the repo[1] and let me know if I'm
missing something obvious, I'd appreciate it.
