Because of various exception frames, it's possible that these things
are being logged out of order.

I can guarantee that if you run out of heap while in a write
transaction then you'll definitely get a lost phase token. I should
have remembered this earlier, but I've seen this often enough myself.

We can run out of heap, particularly when using Lucene indexes. The
only solution I have for the general case is to simply run the JVM
with -Xmx512m. (Or more, but the more heap you reserve the slower it
gets)
