It does not. You can fully expect the universe to go down before that 
happens.

The only reasonable worry is about SHA-1 being broken some time in future, 
i.e. being able to construct a malign version of some source code _which 
has the same hash_. There were plenty of discussions about that; Please 
search the mailing list. (The consent was that those do not matter, 
because an existing object will _never_ be overwritten by a fetch, so you 
would not get that invalid object anyway.)

Hth,
