It's possible to create Template-s from String-s without using
Configuration.getTemplate, and be by bypassing the storage mechanism
and thus the caching. Also, note that the cache not just decreases
I/O, but also prevents the re-parsing of templates. Parsing templates
is somewhat expensive (CPU and GC).

I can't just suddenly make a release... If all you need is a
NullCacheStorage, your implementation is as good as mine. But if you
can give a deadline for me, we can talk about a release.
