Re^3: Adding parallel processing to a working Perl scriptby BrowserUk (Pope)

The problem is that each of the 'fork's, it re-opening the same glob for stdin. Under unix, this works because each fork is a new process, so the re-used glob is unique within its own process space.
But under windows, each 'fork' is actually just a separate thread, within the same process space, so the re-used glob -- despite that it is cloned at the Perl level -- is trying to concurrently reuse the same underlying per-process OS buffers and data-structures; with the inevitable consequences.
When it works, it is by pure chance. Mostly it won't.
