New trace option?

[Ann and Jason Edmeades]

I just noticed there is an option --debugmsg +tid which adds the thread
prefix to the debugmsg trace. I would really, really like a timestamp
prefix - Is this something people would/could find acceptable?

I've hacked a version for my own use using gettimeofday, but anything which
shows seconds or slightly higher resolution would be invaluable. Perhaps a
+time option?

Is this something people would find useful? If so, anyone know a good,
portable way of doing it?
