The code I showed IS threading code. Don't forget that fork creates a new *thread* in Win32, not a new *process*. And this problem happens specifically in Win32.

From perlfork:

The fork() emulation is implemented at the level of the Perl interpreter. What this means in general is that running fork() will actually clone the running interpreter and all its state, and run the cloned interpreter in a separate thread, beginning execution in the new thread just after the point where the fork() was called in the parent. We will refer to the thread that implements this child ``process'' as the pseudo-process.
