Subject: Allocation Failure Tests

These turned up an excessive amount of allocations in CanonData and
CompatData, which have been reduced to two through the somewhat
squirrely use of 'magic numbers'.

There are now allocation tests for every allocated structure in the
library, and they run to completion in a reasonable amount of time.
So, that's nice.
