149: Make Producer<..., SingleCore> Send, like Consumer r=japaric a=BryanKadzban I assume there's no reason that only multi-core Producers are marked Send, while Consumers are not (they're pretty symmetrical). (Context: I'm trying to use an SPSC queue on a single cortex-m0 MCU. So I can guarantee that a SingleCore queue is safe because there is no other core it could possibly be shared with. The RTFM framework adds an assert_send on the producer, since it's shared between init and an SPI receiver interrupt. It also adds an assert_send on the Consumer, since it's shared between init and the I2C transmit interrupt, but that one works since Consumer has this extra C type in the impl already.)
