Strange (spurious?) device failures on Nexus 5X webview perf

Builders failed on: 
- Android Nexus5X WebView Perf: 
  https://ci.chromium.org/buildbot/chromium.perf/Android%20Nexus5X%20WebView%20Perf
- Android Nexus5X WebView Perf: 
  https://ci.chromium.org/buildbot/chromium.perf/Android%20Nexus5X%20WebView%20Perf

Ned, it looks like many of the blink_perf benchmarks on 5X webview perf seem to be failing flakily with cloud storage PseudoLockAcquisitionTimeouts. Here's a link to an example log: https://logs.chromium.org/v/?s=chrome%2Fbb%2Fchromium.perf%2FAndroid_Nexus5X_WebView_Perf%2F1971%2F%2B%2Frecipes%2Fsteps%2Fblink_perf.css_on_Android_device_Nexus_5X%2F0%2Fstdout

Any idea what might be going on here that these are failing all of a sudden?
