Lower memory pressure OOM condition from 30 seconds to 10

Nate Grahamrequested to merge
work/ngraham/oom-faster into master

In conjunction with the default SwapUsedLimit value of 90%, we almost never actually OOM, and instead freeze.

Reduce the time-based condition from 30 seconds to 10 so we OOM faster in a true swap exhaustion situation. 30 seconds is so long the user may force-restart the system, risking damage to the disk.
