From baeb3c1872a989b69eb89fae04f93c59b06f258e Mon Sep 17 00:00:00 2001

Subject: Simply event interface design and make only one pre-process thread.

This makes event pre-processing actually safe for multiple interfaces since multiple events will never be pre-processed simultaneously and the pre-process order is definitely the same as the execute order.
