I kind of like the idea of showing which restart q is bound to, except that
I would probably prefer "2, Q" so that the numbers still line up.

Not sure about confirming the abort restart, just need to make sure that any
code for it doesn't stop me from actually killing it if is in a really
unstable state (and therefore might not do well at running the confirmation
code).

Is there a way to bind 'q', set a particular restart as the default 'exit'
restart? When I'm hacking on UCW there is no "Abort handling SLIME request."

A database error occurred: NIL / 23000
[blah blah blah, yes I know..]
Restarts:
  0: [SHOW-BACKTRACE] Send the client a backtrace page.
  1: [SERVER-ERROR] Send the client an internal server error page.
  2: [GENERATE-BACKTRACE-FOR-EMACS] Generate a bug report in Emacs.
  3: [FAIL-MISERABLY] Pretend this request never happend and fail.
  4: [TRY-AGAIN] Play this request over from the top.
  5: [TERMINATE-THREAD] Terminate this thread (#<THREAD "an httpd worker 0"
{BD6A939}>)

I'm thinking 'fail-miserably which just closes all the streams and shuts
down would be a good one to bind.

I looked around a little bit, it doesn't look like this is currently
available. Q invokes slime's sldb-quit, which calls swank:throw-to-toplevel.
Maybe add a new parameter that defaults to 'abort-request, but could be
dynamically rebound to name a different restart before UCW invokes the
swank-debugger? Swank:throw-to-toplevel would use the parameter to invoke
the correct restart.

Any objections/much better ideas?
