At that point, Polipo will set object->length to the now-known content
length, and call objectMetadataChanged, which calls dirtyDiskEntry, which
will cause a Content-Length entry to be written out.

Polipo should consider the file as partial in that case.

Looks like a bug.  Could you provide a trace of the HTTP exchange?
