Future-core-preview-0.3.0-alpha.12 fails to build on new nightly

[kitsuneninetails]

Due to commit: rust-lang/rust@d9a4b22#diff-31ce1b2eb51b1e216232d2d4770b8f92 which removed LocalWaker (and others), futures-core-preview now fails to build with:

Wait #1445 merged

Thanks for the link!

Anyone: Any ETA on #1445? It's already been over 2 weeks.

It sounds like it will take a while for this breaking change to be fixed (I would normally say this should be a super-high-priority, but I understand "things" happen :)).

I'll pin my Rust toolchain prior to the above commit until it's all working again.

Thanks!

Alpha 13 was released a few days ago, so this should be fixed. Let me know if you run into any problems!
