why not? couldn't libcurl ftell() before the first header set and
fseek() there before each following header set? at least as an option.

i'll try that. (i see a potential problem where i wouldn't know what
was a header set and what wasn't. suppose the body contains a header
set of it's own (as if i had tried to access the file "out" from my
example thru http). how do i know it's not a real header set...
libcurl knows it internally, but i'm not sure it's possible to deduce
that afterwards. or perhaps the http spec has solved this somehow.)

i would if i had any idea how to make patches...
