I am not sure priority is needed in libcurl. But I plan to implement
it at darcs level as you proposed earlier.

Idea is to have a pipe length limit in darcs, we download no more than
this limit at a time. Darcs stores a list of urls which were requested
for download, but not yet passed to libwww/curl.
When new url is requested for download we just append it to this list
to beginning or to end depending on priority.
