I don't agree. Also, it is faster than object monitors. This was proven 
by David Simcha recently where he sped up GC allocations by some 40%-ish 
factor just by changing to a final class derived from core.sync.mutex. 
And no, that's not a bug in the monitor implementation. It's a 
limitation of the design.
