Please make no more changes to the RC_1_31_0 branch without the release 
manager's permission. The one exception is removal of is_abstract code.

We need to be totally stable so that the regression tests can cycle one 
last time.

PS: For the next release, we need to define written "release discipline". 
What kind of changes are allowed at various points, such as after branch, 
after release candidates start, etc.
