Re: [dev-context] texexec --timeout=NN should return nonzero code on timeout

Here is what has come up from the regression testing.  [I'll send them
one issue/email.]
If a texexec job runs out of time (--timeout=NN), the exit code should
be nonzero.  Right now it's zero; which, I just realized, had slightly
confused the error handling by the regression-testing.
def timedrun(delay, &block)
        delay = delay.to_i rescue 0
        if delay > 0 then
            begin
                report("job started with timeout '#{delay}'")
                timeout(delay) do
                    yield block
                end
            rescue TimeoutError
                report("job aborted due to timeout '#{delay}'")
                setvariable('error','timeout')
            rescue
                report("job aborted due to error")
                setvariable('error','fatal error')
            else
                report("job finished within timeout '#{delay}'")
            end
        else
            yield block
        end
    end

should do that (in base/tex.rb)

Here's an example using one of the problematic files in the test repo.
[Send the output to a file because it's grows to 14MB.]  This command
texexec --nonstopmode --timeout=10 tex/context/base/unic-002.tex/test-001.tex
exits with error code 0, but this one
texexec --nonstopmode tex/context/base/unic-002.tex/test-001.tex
exits with error code 1.  Maybe if it times out it should exit with its
own code (who knows, maybe 23?).
[I'm testing the above with 2007.01.23]
So I wrote a short Python script (utils/run-it.py in the repo) to handle
maximum time and maximum filesize, which the Makefile now uses to wrap
the texexec call.
