[Mono-list] How does Monitor.Enter work?

[imays]

I got a question how Monitor.Enter works. I investigated .net framework
source code, and it shows this only:

        [System.Security.SecurityCritical]  // auto-generated
        [ResourceExposure(ResourceScope.None)]
        [MethodImplAttribute(MethodImplOptions.InternalCall)] 
        private static extern void ReliableEnter(Object obj, ref bool
lockTaken);

I guess Monitor.Enter implementation is platform dependent, so I browsed
Mono source code and I gave up :(

Yes, a critical section assigned for each System.Object instance may solve,
but, I don't think the actual Monitor.Lock is written like this, because
creating a critical section for each System.Object will cost unlimitedly.
(Win32 does not allow billions of critical section objects in a process!)

Does anybody know how Monitor.Lock works? Please reply. Thanks in advance.
