If the script is short lived, and turning GC completely off is
an acceptable option, it's the most predictable way. It is possible then to

How is it possible to know how long the GC will take, even if you run it
at known times?

If you know how much allocated data there is, and you know that collection
will not be delayed (e.g. because of __gc finalizers), then you have a
known upper bound on mark&sweep time.
