"When the filesize is known from content-length header, safe_fread is
always told to read sizeof(buf). This waits until the underlying fread() to time-out for the last part of the downloaded body. Fix this by sending the number of remaining bytes to read when known." - junkio@ I reworked the logic in his patch
