I hit this assertion

swift-nio/Sources/NIOPosix/BaseSocketChannel.swift

Line 1077 in 324bc65

assert(self.lifecycleManager.isActive)

when running the NIO tests in a tight sandbox. Output

     Test Suite 'All tests' started at 2023-07-11 05:46:11.149.
     Test Suite 'swift-nioPackageTests.xctest' started at 2023-07-11 05:46:11.153.
     Test Suite 'AcceptBackoffHandlerTest' started at 2023-07-11 05:46:11.154.
     Test Case '-[NIOPosixTests.AcceptBackoffHandlerTest testChannelInactiveCancelScheduled]' started.
     swift-nio/Tests/NIOPosixTests/AcceptBackoffHandlerTest.swift:268: error: -[NIOPosixTests.AcceptBackoffHandlerTest testChannelInactiveCancelScheduled] : XCTAssertNoThrow failed: threw error "bind(descriptor:ptr:bytes:): Operation not permitted (errno: 1)"
     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).
