Memory leak: possibly caused by bindings

[Jaifroid]

Please see initial discussion at kiwix/kiwix-js#872.

I corroborate a memory leak, which is particularly evident when loading and searching with large ZIM archives. After loading more than two ZIM archives (in succession), only using libzim for the Xapian full-text search, an app is prone to crashing with an Emscripten "cannot enlarge memory" error.

If anyone has any clues on how to debug this kind of thing, I'd be very grateful to hear them.

Memory leak seems particularly problematic when switching between NODEFS and WORKERFS inside Electron framework. When using only the WORKERFS and only for Full Text Search (for now), the leak seems to be sufficiently under control to be useable in an implementation.
