timeout = timeout.Add(new TimeSpan(0, 0, 1));
Console.WriteLine("Changing the timeout interval to {0}",
timeout);
if (timeout.TotalSeconds <= MaxTimeoutInSeconds) {
// Pause for a short period.
Thread.Sleep(250);

// Write to event log named RegexTimeouts
try {
if (! EventLog.SourceExists("RegexTimeouts"))
EventLog.CreateEventSource("RegexTimeouts", "RegexTimeouts");
EventLog log = new EventLog("RegexTimeouts");
log.Source = "RegexTimeouts";
string msg = String.Format("Timeout after {0} matching '{1}' with '{2}.",
e.MatchTimeout, e.Input, e.Pattern);
log.WriteEntry(msg, EventLogEntryType.Error);
}
// Do nothing to handle the exceptions.
catch (SecurityException) { }
catch (InvalidOperationException) { }
