BaseSocketChannel: assert(self.lifecycleManager.isActive) hit when running NIO tests in sandbox #2465
Description
I hit this assertion
when running the NIO tests in a tight sandbox. Output

NIOPosix/BaseSocketChannel.swift:1077: Assertion failed
The sandbox disallows bind and other network related stuff. So it's expected that the tests fail but I wouldn't expect an assertion to be hit.
This can probably be tested with the SAL (syscall abstraction layer) because that should make it easy to make bind fail with EPERM (== 1).
