It's a bug.
It may be more of a conceptual bug than a code error. The "size" of
the stdout file stream is not knowable, so the file size test in
StandardFileStream>>closed does not really make sense in the context
of an output stream that typically is not attached to a file.
Having said that, I see this result with the classic interpreter VM
on an updated image (trunk level update but old V3 image format):
OSProcess thisOSProcess stdOut closed ==> false
FileStream stdout closed ==> true.
And with the current Cog/Spur on a similar level image:
OSProcess thisOSProcess stdOut closed ==> true
FileStream stdout closed ==> true
So at one time, the test worked correctly with OSProcess.
So maybe there is a way to have it work as expected with FileStream>>stdout
(and OSProcess again). I suspect the differences may be related to
VM changes in the SQFile data structure, but I have not checked to
confirm.
