This is my impression as well. It looks like the memory handling of PHP
(and the garbage collection process) really has improved lately.

Disclaimer: The usage patterns from running all unit tests of e.g. the
core does not represent the real memory consumption of real use cases.
When running lots of unit tests, there is a huge number of extremely
short-lived objects (most of them live just for the duration of a single
request), whereas in real use cases most (non-local) objects live until
the end of the request.
