Start test with eventfd method at Thu 26 Apr 14:58:34 CEST 2018
Starting MiniBrowser.
Triggering fake memory pressure events each 10.000000 seconds. Unset WEBKIT_MEMORY_INTERVAL_TRIGGER to use real memory detection
Using patched eventfd method to deliver messages. Set WEBKIT_MEMORY_PRESSURE_USE_INTERNAL_IPC to enable IPC method
in-WebProcess  memory monitor disabled for testing purposes
