The recent testing of AT showed quite bad behaviour, so it cannot be
released as-is.  We will have more capability for testing this internally
very soon, and I think that LLNL is also moving to test a newer version
of Lustre so this should allow resolving the issues with adaptive timeouts
more quickly.

For the 1.6.5 release we plan to disable AT only with a configure option
instead of reverting the code entirely (unless of course we get a lot of
testing and some bug fixes very soon).  This will allow testing AT more
easily.

Cheers, Andreas
