Error while compiling futures-timer

This is fixed in async-rs/futures-timer#23. It seems necessary to bump futures-timer version.

[ibaryshnikov]

Tide doesn't depend directly on futures-timer, in addition cargo tree produces

Oops, I missed it.
It seems that futures-timer has already been updated in the master of runtime, so I think that it can be fixed by temporarily adding the following block to Cargo.toml (this must be removed before release).

[patch.crates-io]
runtime = { git = "https://github.com/rustasync/runtime" }

[ibaryshnikov]

After doing this I got

warning: Patch `runtime v0.3.0-alpha.5 (https://github.com/rustasync/runtime#19a1a825)` was not used in the crate graph.

Published runtime version is 0.3.0-alpha.6, but in master it's still 0.3.0-alpha.5
https://github.com/rustasync/runtime/blob/master/Cargo.toml#L4
And tide depends on -alpha.6
https://github.com/rustasync/tide/blob/master/Cargo.toml#L59
