What about things like sqliteMemory?  We should be exhaustive here to avoid
regressions.

Done.

[Charlie Reis, 2012/04/27 22:01:56]

Could just call validateProcessPropertiesOnUpdate, since this should be a
superset of that.  (We can move the assertFalse(privateMemory) outside of that
one, or use a boolean flag to say whether we want it to be present or not.)

I've rewritten the whole process validation.
