Requesting merge to 52, as this change sets the desired timeout for the functionality introduced in  issue 606979  (which already went into 52).

The change here is pretty straightforward: it's just halving the hardcoded timeout interval.

Your change meets the bar and is auto-approved for M52 (branch: 2743)
