That happens because when the interpreter shuts down, it deallocates all the Perl structures one by one, effectively writing to the memory where they are stored.

Under Unix/Linux, that means that as the memory is write-accessed, the kernel has to perform a copy-on-write of the underlaying pages.

As a workaround, try calling _exit or exec "/bin/true"; at the end of the END blocks.
