That depends on how you define "non-deterministic". If it's "anything
that is difficult/impossible for a meta-build system", then no, we do
not agree ;-).

Concrete example: Apache Thrift generates a dynamic set of C++ source
files, one for each service defined in the input file (plus I think for
some other language constructs). This is impossible to handle cleanly
in a meta-build system unless the underlying build system can handle
it natively. Is this case considered deterministic on not?
