Sounds about right.  I suppose all those cases that you aggregated here
would expand to full tags in the actual code.  I furthermore suppose
that some of these could be ignored, such as the transaction ones and
things like load, lock, move, fetch, discard, deallocate (maybe lump
them all together under "other", or some other rough categorization, as
Tom suggests).  Also, for many of these commands it's probably relevant
whether they are acting on a temporary object or not; we should either
count these separately, or not count the temp ones at all.
