Well, the reason is that inder Windows, scripts executed by an HTTP
server (such as Apache or IIS) run in threads, so it's possible for
multiple instances of a script to run under the same process ID (even
though the thread ID is different). With command-line execution, no
threading takes place; each instance has its own process ID...
