The SocketPlugin implements asynchronous I/O for all platforms, so
socket operations are nonblocking.
OSProcessPlugin also provides nonblocking I/O, but only on unix/mac
platforms at the moment. AioPlugin implements the aio interface to
enable notification of a Squeak semaphore on data availability.
These are used in OSProcess and CommandShell for nonblocking I/O
on files and pipes, especially for interprocess communication using
