Maybe take a look at how company-capf caches the results of calling a 
CAPF function?

Depending on the data, the cache key is either 
buffer/point/chars-modified-tick tuple, or the "completion session" (but 
in a company-mode specific way).

For CAPF and Company, we also discussed the idea of a "session object" 
some time ago, but that's not in the current API so far.
