…nput long tail (pythonGH-149003) pythongh-141473: Speed up test_communicate_timeout_large_input Replace the slow reader's 30s sleep with a parent-driven wake over a loopback socket so post-timeout communicate() doesn't block waiting for the child to wake on its own. Worst-case runtime: ~30s -> <1s. (cherry picked from commit e1384cf) Co-authored-by: Gregory P. Smith <68491+gpshead@users.noreply.github.com>

gh-141473: Speed up test_communicate_timeout_large_input
Replace the slow reader's 30s sleep with a parent-driven wake over a
loopback socket so post-timeout communicate() doesn't block waiting
for the child to wake on its own. Worst-case runtime: ~30s -> <1s.
