impl Sync for T: Send

[GTRI-nathan]

Cool crate!
When using it, I had to modify Mutex to add a line like https://doc.rust-lang.org/src/std/sync/mutex.rs.html#182 from the std Mutex implementation, as I was using a data type that was Send but not Sync.
I opened this issue as it seems like the API difference from std might be a bug.
Best,
Nathan

Thanks for the report, fixed it for both Mutex and RwLock. Published on crates.io as version 1.1.0 :)
Hope this crate helps :)
