declare() calls that aren't followed by commit() are applied at the end
of the provision script. This change defers those until all provisions
have been executed. This prevents certain cases of preset loop faults.
This can be used to ensure parameter refresh times are aligned (as
opposed to using Date.now() - X). It also allows for possible future
optimizations by exploiting the fact that the value of Date.now(X)
remains static for a given amount of time.
The variance value can be used to shift the discretization threshold
points based on the hash of the device ID for load distribution.
The djb2 hashing algorithm has been replaced with MD5 for better
distribution.
