Subject: [PATCH] UMD: Prevent ResourceCleaner timeout overflow on libstdc++
Avoid passing the max steady_clock time_point to cv.wait_until, which
can overflow internally on libstdc++ and cause undefined behavior.
Instead, use cv.wait() when no timeout is set, only computing an
actual wait_until deadline when a real idle timeout is active.
