The main point of :shared is not to save memory, but to allow multiple
threads access to the same data. From perlthrtut:
Also note that under the current implementation, shared variables use
a little more memory and are a little slower than ordinary variables.
Each shared var has an emptyish SV per thread which has attached magic
that allows it to access the contents of the real var.
