Both server implementations are a single process single thread implementations. They handle one connection at a time, waiting for input and echoing it back. Fork-related problems on the Win32 platform should not be the problem since fork is not used.

The comment about telnet running as another process is totally irrelevant since all programs mentioned were running as independent processes.

Different perl programs do not share the same process the way some browsers do. Every program is run as an independent process, and just because one perl program is blocking does not mean all perl programs would block.
