rootfs is populated by unpacking a .cpio archive that is combined with the kernel. What frees the original .cpio archive after it is unpacked? I can't find the code. Deleting the content of the unpacked rootfs isn't the same thing.

rootfs isn't always populated by an archive embedded within the kernel. It can be an external file. However that said, while I don't know exactly how the kernel handles this, there is nothing that forces the kernel to remain in memory. The kernel controls the memory, it can do whatever it wants. If it wants to release the portion of memory used by the image, it can.
