Yes, it does. If it didn't, you'd deadlock when the pool reached the maximum
size.

What you see is that the "Objects" statistic in the component services
manager doesn't actually mean number of objects, but rather the existing
number of connections; that is, the number of client side stubs connected to
the application, whether they are attached to an active object or not. What
you see is that you're probably ending up creating stubs even if they are
not needed, and those will drop after a gc (that happens because you're not
reusing the client side references to the objects bur rather discarding
them).
