I feel *strongly* that there is a lot of completely unnecessary (and
is some cases, outright useless) churn in this diff.  Please stick to
functional changes.

At any rate, I do not see the special case handling for `main program'
symbols to be particularly beneficial.  It makes the simple case
slower, and it does not help enough in some of the complex cases
(e.g. rep or xmms, where most libraries are loaded through dlopen(3)).
