Patch ID	: P95041001
Summary		: Fix lock ordering under trace command
Status		: Mandatory
Date		: 04/10/95
Release		: OS 4.1C
Architectures	: Series5 Series6
Affected bugs	:

Changed files	:
	kern_synch.o 1.10
Problem Description:
	Lock ordering was violated in the kernel during traced commands, 
resulting in processing slowdowns while lock debugging error messages 
were written to the system log. The condition may be re-created with 
the following:

        set x = 1
        while ( $x < 10 )
        trace ls &
        @ x += 1
        done
	end

The LOCK_STYLE rom variable must be set to "debug" prior to boot.
