ah, well now I've got 68 runs with an event amd /slight/ expansion of the giant lock -- in InnerWait I .release before Leave(giant).<BR>
Given that release almost immediates enter giant anyway, that doesn't seem a bad move.<BR>
<BR>
It didn't hang at 68, it did:<BR>

I'll try again having put back the semaphore..<BR>
I rather suspect I have it fixed though and have uncovered some other problem.<BR>

Tony..this semaphore with a maximum value of 1, that is a strange thing, isn't it?<BR>It could just be an event, right?<BR>I tried that..it took 50 runs to hang Juno..<BR> <BR> - Jay<BR> <BR>

ps: while I consider the whole stacksize thing broken anyway, notice that using an idle thread (which you had no choice about) got you an indeterminate stack size.<BR> <BR> - Jay<BR><BR>
