Thanks Robert. I wasn't thinking properly about it. I believe you were
correct in saying most everything loaded before doing a simple puts is
just C code...the more I thought about it (and after running strace to
verify), it seems that no external ruby libs are loaded up by the
interpreter assuming that your code doesn't do any specific requires.
So, the code I showed gave no results correctly...but if you change it
to:

$ ruby -rtrace.rb -e 'require "net/http"'

You get the expected results. So, in lieu of having rubinius, I think
that's the best you can expect. Everything else you'd have to dive
into the C for. And honestly, I don't really care about the C...I'm
more interested in being able to debug libraries and gems that are
more promiscuous than they should be.

I appreciate your help and guidance.
