I took a bit of time last year trying to create a UML diagram of the
various internal curl data structures. I eventually gave up after struggling
in vain to make sense of the complexity. I'm attaching an image of what
I did manage to pull together, which hopefully gives you something to start
from.

Agreed! But the current code base has stood the test of time in that it
not only works, but works (mostly) in the face of out of memory errors and
complex protocol scenarios. The existing test suite will help to give
confidence to any restructing that takes place and will hopefully help to
avoid any regressions.
