Research direction

Start with the test failure AssertionError: Didn't reach a full buffer in the linked ppc64le build log, then compare the failing behavior between uvloop 0.18.0 and 0.17.0. Reproduce it on ppc64le and check whether it differs from the other listed platforms; done means the test passes reliably without masking the underlying failure.

Written by the indexing model from the issue text.

uvloop version: 0.18.0 (from tag v0.18.0)
Python version: 3.11.6
Platform: ppc64le
