# Test 1: Buffer accessible from resident device (dev1) - should always work
dev1 = Device(1)
dev1.set_current()

This stream is used for test2, can we move the creation underneath the test 2 comment?

dev1 = Device(1)
dev1.set_current()
dev1_stream = dev1.create_stream()
PatternGen(dev1, NBYTES).verify_buffer(buffer, seed=False)

Just a note that PatternGen uses unified / managed memory underneath it where I suspect this may give us some pain / troubles on Windows?

Side remark: I'm working on getting rid of that distraction under #1565

In the meantime we discovered that the root cause is much deeper.

I saw @testcupy closed the internal PR. Closing this copy, too.
