Is there a way out if you do that?  Does QUIT work?  Also, does print
<tab> read all symtabs?

I'm not happy with introducing this slowdown.  I'd like to at least
see a profile first - of some smaller example!  But I guess you're
right that -readnow is not useful; maybe I should just let go...

I thought I did -readnow profiling on my previous patches in this
area without introducing such a big slowdown, but I don't know that
for a fact.
