How about the attached patch?  It adds an informational message after 30
seconds by default.  With a "--timeout N" flag, we instead display a
message and exit (after N seconds).

Note that:

1. I didn't yet add documentation.
2. I've only tested the patch on GNU/Linux (*not* on MS-Windows).
3. To simulate a timeout for testing, you could try this:

diff --git a/lisp/server.el b/lisp/server.el
