From 44038491264a350a8849e1d7e8547bbdec134d74 Mon Sep 17 00:00:00 2001
From: Adam <Adam@anope.org>
Date: Fri, 7 Jan 2011 15:57:13 -0500
Subject: Added db_mysql_live which allows Anope to pull data from the four
 main SQL tables in realtime, which effectively gives us "live" SQL. Changed
 eventfd pipe engine to not use buffered write. Added TryLock to threading
 engines. Made blocking SQL queries in our SQL API thread-safe.
