I was there when we first made the decision not to cache it. It was
taken quite conciously. Also, I have little recollection of any thread
with the outcome as you put it, so I searched http://svn.haxx.se/ but
all I seem to be able to find is people saying "we don't agree with
your process, so why would we agree it needs automation?"...

Could you provide a pointer to the thread you're referencing here? For
additional background reading?

I think we have bigger problems than this, at least for now. Next to
that: in Open Source everybody scratches his/her own itch. If you want
to change the libraries to do this, the sources are yours to do it.

(However if you want to achieve mainline integration, you're invited
to discuss your proposed (code)changes on the development list...)
