Old description:



New description:

 If a port has multiple master_sites listed (either explicitly or
 implicitly through the likes of sourceforge), we should consider splitting
 the file download chunks into pieces.

 The size of the file can be determined with a curl header call and then
 even portions distributed to each download.  In the future, we can use our
 ping calculations to fuzz this off even segments to chunks that are
 fitting for the ping times.

 This feature should likely be implemented as opt-in, since most users
 don't expect to attempt to fully saturate their bandwidth.
