I figure we need to introduce a way to get a larger download buffer when a
specific protocol (such as sftp and scp?) is used. Currently the buffer is
part of the SessionHandle struct but we'd need to make it get allocated
separately and then realloc() on demand for this kind of situation.
CURL_MAX_WRITE_SIZE in include/curl.h would also need to be bumped to have the
largest possible size.
You in the mood to work on a patch for this?
