Well, kind of.

I guess the two bugs are different. Maybe I did not write the bug text
specific enough. In bug 115535 I wanted to see how the code behaves when
the each of the two "listeners" enters a loop but the "trigger" does not
and tries to destroy the semaphore. Apparently in this case the trigger
cannot run until completion. I think the bug is the destroySemaphore
method. When it sees that the "share count" is non-zero it executes
nothing.

In bug 113589 both the listeners and the trigger will run in a loop.

The two bugs may be related. I am not sure now.
