To the extent that it can be fully plumbed in all its complicated glory,
yes. :)   A weekend-work in progress, though taking about 5x longer than
originally thought.  But it's coming along. Got a lot done the last couple
of weekends.

Yep, got it now, thanks.  Between your explanation here and building an 
instrumented version from git to dump c->server_list and a few other items,
I think I've finally got a reasonably clear handle on the whole of
pa_context_connect() and friends.

(And I should add that after having wandered thru the code a bit now, I
sympathize with your earlier footnote. :)

Btw, if it's of any use to the project, attached is a heavily commented version
of pa_context_connect(). That's what I'm using in the writeup as the basis
for both a high-level description and a more detailed discussion. (That 
commented version will be included in the writeup pretty much as-is.)

If you or Tanu have time to look thru it and let me know if any of the
commented understanding there is wrong, it would be greatly appreciated.

Thanks again for your time on this.

Glenn
