Or, if you know python, you can do this:

1) go to http://code.google.com/p/freebase-python/

2) check out the 'freebase-api' from source (sorry, no downloads)

3) install the freebase-api in your python environment (python setup.py 
install or something like that)

4) use the following code

-------------------- cut here --------------------------

#!/usr/bin/env python

from freebase.api import HTTPMetawebSession, MetawebError

query = {
  ... put your mql query here...
}

freebase = HTTPMetawebSession('freebase.com')
iterator = freebase.mqlreaditer(query)

for topic in iterator:
   ... do something with the returned topic, one by one ...

--------------------- cut here --------------------------

Note how the 'query' needs to be for a single topic, not for many (I'm 
telling you because I got burned myself the other day).

I've been using scripts like the above to obtain dumps of particular 
subsets of the freebase graph and it works with cursors, so timeouts are 
not a problem (which is what Will used).
