Subject: [PATCH] LWP failed to wake up threads sleeping in empth_sleep() while
 other threads were runnable.  This let players with a sufficiently fast
 connection starve out system threads, including the update.  Fix: [EMPTH_LWP]
 (lwpWakeupSleep): External linkage. [EMPTH_LWP] (lwpReschedule): Call it.
