Which platforms have limited buffer sizes?

Question

The Groovy Process Management page mentions that:

Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock

This snippet comes from the JDK API. Which platforms, in particular, are these?

Answer 1

I know this happens on Windows at least. This is why a child's stdin and stdout must be read in another thread.

Answer 2

It also happens on Linux and (I expect) Solaris.

In fact, I would be surprised to find any conventional OS platform that provides unlimited buffering for process-to-process streams; i.e. pipes in UNIX terminology.
