    this is a somewhat reasonable compromise until one day we unify Put/Delete in an object
hierarchy and fix up the API a bit.

> Currently HBase has support for atomic checkAndPut operations on individual rows. It
would be very useful to also support atomic checkAndDelete. I have added support for atomic
checkAndDelete to trunk and will provide the corresponding patch tonight after I merge in
any upstream changes from the last few days.
