void webkit_memory_pressure_settings_set_strict_threshold ( WebKitMemoryPressureSettings* settings, gdouble value )
Sets the memory limit for the strict policy to start working.
value as the fraction of the defined memory limit where the strict
policy starts working. This policy will try to reduce the memory footprint by
releasing critical memory.
The threshold must be bigger than 0 and smaller than 1. Also, it must be bigger
than the conservative threshold defined in
