+Subject: [PATCH] tests: wait for background specs syncs instead of assuming a
+ 1ms interval
+
+`StatsigOptions.specs_sync_interval_ms` is now rejected below 1000 ("Invalid
+'specs_sync_interval_ms', value must be greater than 1000"), so the five tests
+that set it to 1 no longer get the near-instant background sync they were
+written against. They fail at the 0.22.0 tag on every platform, against the
+wheels published on PyPI -- x86_64, aarch64 and macOS alike.
+
+Use the smallest accepted interval and wait for the condition each test is
+really about rather than for a fixed duration. The waits return as soon as the
+sync lands, so fast hardware pays nothing and the whole file gets quicker.
+
+Upstream-Status: To upstream [not yet submitted; the release tag is not covered by upstream's test workflow, which runs on branches only, so this needs a maintainer discussion rather than a drive-by PR]

+Subject: [PATCH] tests: give fork_runner.py a timeout a slow machine can meet
+
+`fork_runner.py` performs 50 full SDK initialisations -- ten iterations, each
+followed by four nested forks that initialise, evaluate and shut down -- against
+a local mock server. Ten seconds is enough on upstream's x86_64 CI and not on a
+riscv64 runner, where the subprocess is SIGTERMed part way through and the test
+fails with `assert -15 == 0`.
+
+`communicate()` returns as soon as the subprocess exits, so a larger budget
+costs nothing where the old one was already sufficient.
