[Vm-dev] Unoptimal #signalFinalization: ?

It looks like that implementation of the above metod is not optimal:

signalFinalization: weakReferenceOop
	"If it is not there already, record the given semaphore index in the
list of semaphores to be signaled at the next convenient moment. Force
a real interrupt check as soon as possible."

	self forceInterruptCheck.
	pendingFinalizationSignals := pendingFinalizationSignals + 1.

This method is invoked when GC detects some died object for given weak
If i remember correctly, VM forcing interrupt check after each GC anyways, so
	self forceInterruptCheck.
is just a waste of cycles here.

Best regards,
