passing around arrays of those may quickly exhaust the JS

+
+ TODOs include, but are not limited to:
+
+ - The ability to manage multiple DB handles. This can
+ potentially be done via a simple mapping of DB.filename or
+ DB._pDb (`sqlite3*` handle) to DB objects. The open()
+ interface would need to provide an ID (probably DB._pDb) back
+ to the user which can optionally be passed as an argument to
+ the other APIs (they'd default to the first-opened DB, for
+ ease of use). Client-side usability of this feature would
+ benefit from making another wrapper class (or a singleton)
+ available to the main thread, with that object proxying all(?)
+ communication with the worker.
+
+ - Revisit how virtual files are managed. We currently delete DBs
+ from the virtual filesystem when we close them, for the sake
+ of saving memory (the VFS lives in RAM). Supporting multiple
+ DBs may require that we give up that habit. Similarly, fully
+ supporting ATTACH, where a user can upload multiple DBs and
+ ATTACH them, also requires the that we manage the VFS entries
+ better. As of this writing, ATTACH will fail fatally in the
+ fiddle app (but not the lower-level APIs) because it runs in
+ safe mode, where ATTACH is disabled.
