Consider decreasing distlock retry timeout

If we have a thread that tries to newly acquire the distlock on an aggressively quick cadence (less than a second), it's possible that threads that have been waiting on the distlock can get crowded out by the new request. We should decrease the retry timeout, so that retrying threads can have a more equitable chance to acquire the distlock.

This ticket may alternatively act as a placeholder for more preferable solutions to the linked BF.
