Recording unusual behaviour in UDB

UDB uses our LiveRecorder technology internally.  This means that if you encounter a problem with UDB, you can make a recording of some of the internal UDB processes and then send those to us so that we can determine what the problem is.

You can instruct UDB to make these recordings using the following steps:

1. Set the following environment variables when running udb: UNDO_lr_nanny_filename=nanny.undo, UNDO_lr_server_filename=server.undo
2. Reproduce the problem.
3. Use the Undo Upload Service to send the resulting nanny.undo and server.undo files to Undo's support.
4. Relax while we debug an exact copy of the bug in our code.

Note that the recordings will not contain any sensitive information from your debugged application.
