Robert Muir updated LUCENE-3291:
--------------------------------

    Attachment: LUCENE-3291_test.patch

here's the test, it indexes 26 terms (a..z) per doc about 80M times to create 
just over Integer.MAX_VALUE t-d pairs.

with memorycodec (ant test-core -Dtestcase=Test2BPostings -Dtests.codec=Memory) 
it fails like this:

> While working on LUCENE-3290, I noticed a readVint that i thought should be a 
> readVLong, so I wrote a test (Test2BPostings)
> to try to catch things like this... it takes about 5 minutes to run with 
> MemoryCodec.
> The problem is, it dies on some other bug in FSTs first!
