Why would you need a _finally?
Can the variable-access throw?

>try... __finally to ensure that a critical section is always released?

If so, how about a CS class of some sort?
(May be typing/logic/C++ errors)

ret_type Getter()
{	CS	cs(MyThreadCS);	// constructor enters critical section
	return	this.value;
}			// destructor releases critical section
	
class CS
{	LPCRITICAL_SECTION lpCriticalSection;
	CS(LPCRITICAL_SECTION CriticalSection)
		lpCriticalSection = CriticalSection
	{	EnterCriticalSection( lpCriticalSection ); }
	~CS(){	LeaveCriticalSection( lpCriticalSection ); }
}
