Several things.....
1> you're allocating a new bitset each time around. Do it outside the loop.

Something like (but I haven't tried it in this form)
Term term = new Term(blah blah blah);
TermDocs td = ir.termDocs(term);
BitSet bits = new BitSet(reader.maxDoc());
while (td.next()) {
bits.set(td.doc());
}
