But the generic completion code can't easily go down to a single call in
the general case.

Obviously it can, via caching. Most completion tables which incur
a significant computation code should use caching, but we can't use
caching unconditionally, because it's hard to come up with a general
conditions under which the cache can be reused or needs to be flushed.
As mentioned, we could try and provide a generic completion-table cache
so as to make it easier to write completion tables that have
a significant computation cost. Patches welcome.
