>     (try-this-for SECONDS BODY)

The best way to do this is to build the timer check into 'body'
itself. That way you can be sure to always exit in a known state. If
an external timer interrupts 'body' (and I haven't yet figured out how
to do that, so it's in theory) then the state could be in some
disorder.

Of course if 'body' is something like an internal emacs call that
simply might run for a long time, this idea won't work.

If 'body' is running a /process/, however, an Emacs timer can trigger
a call to 'kill-process' or 'interrupt-process' to halt the process.

Don't know if any of this helps ...
