Signal safety?

[akhilles]

From my initial inspection, it looks like Sender::try_send is safe to use inside signal handlers. If this is case, it might be worth documenting since it's a compelling alternative to signal_hook::iterator::Signals.

Not quite - Sender::try_send() might allocate, and allocation might grab an internal lock inside the allocator, do syscalls etc. So it's definitely not signal safe :)
