What's the point of this anyways? Unless you're unlike most uses, you're
using the default hashing, which is [drumroll please.....] SHA-1.

Throwing asside repudation, it still takes is 8 bytes to collide an
md5sum, and about 8 and a half bytes to collide a sha1sum...  I suggest
that anyone that is worried about this problem run the following
program: 

main.c: 
int main() {
  unsigned int x,y;
  for (x = 0; x < 2^32; ++x) for (y = 0; y < 2^32; ++y);
  return printf("Now you can worry\n");
 }
