You may know, in principle backporting is for bug fixes.
And even if 1.9.3 backport this, 1.9.2 and 1.8.x still needs ffi.
This means your pain won't decrease, will it?

The attached patch allows Zlib::Inflate users to supply dictionaries ahead of time in order to avoid handling the Zlib::NeedDict exception.

Multiple dictionaries may be provided.  Zlib::Inflate will choose a matching dictionary based on the adler32 checksum of the provided dictionaries.
