Hi Peter,
Sorry to have taken so long to get back to this thread on
SelectableChannels for process I/O.
Working on the pipelines idea got me back to thinking about this proposal.
One bit of spec/implementation to address is the state of the In/Out/Err
streams
of the process when using Redire
I have internalized the idea that finalization is a method of last resort.
If there's a chance to free some OS resource by doing some work NOW, do it,
and don't leave it for a finalizer to do later.

Hi Martin,
That sounds like finalization of the FileDescriptor, but perhaps a
mechanism built on PhantomRef
would be easier enough to maintain and can leave the data in the pipe.

Hi Peter,
I don't know the history behind the stream draining in ProcessImpl.
I understood it to be a performance/scalability issue.
Maybe Martin, Alan, or someone else can fill in the history.
