synchronized with multiple arguments

[Andrei Alexandrescu via Digitalmars-d]

A reader reminded me (thanks!) that in TDPL synchronized with multiple 
argument does the right thing - locks objects in increasing order of 
address.

So now to everyone's unpleasant surprise, the sample code in TDPL 
compiles and runs, it just has difficult to detect problems.

So regardless of the discussion of the comma operator, synchronized with 
multiple arguments should just work.

Is synchronized being lowered to some function calls?
