Upgrade from 1.1RC1 to 1.2RC1 eventually fails if documents have lots of objects OR lots of history

Logging the issue so that it can be tracked and resolved.

On upgrading from a working 1.1RC1 xwiki installation, the conversion process begins and can be monitored in the log files.
For all but one of our xwiki databases, all worked relatively ok (120mins a bit long, but doable).
The main xwiki database (our "master for all the virtual wiki's, and co-incidentally our largest database) does not finish, and crashes our. While it was running, it was observed that several documents take over 90minutes each; these documents are unique in that they have 350+ history revisions, and a large collection of objects. We can't remove them either as they're in-process project documents. The main xwiki database has clocked in at over 28 hours without completing.

Below is a sample set of the errors we have been receiving:
