Issue Description:

Swift 3.0: read()ing from a DispatchIO channel on Linux results in a SIGILL:

  • thread Add & use DISPATCH_NOESCAPE attribute macro #6: tid = 1146, 0x00007ffff7efb503 libdispatch.so`_os_object_release + 35, name = 'sockd', stop reason = signal SIGILL: illegal instruction operand

  • frame #0: 0x00007ffff7efb503 libdispatch.so`_os_object_release + 35
    frame Typos #1: 0x00007ffff7ef46b7 libdispatch.so`_dispatch_call_block_and_release + 7
