OK, clear. thanks for the explanation.<br>
<br>
I have currently put a while 1: around run(), that works for now. I am
still getting discarded channel data in there, but I seem not to be
losing anything there.<br>

<div>Run first removes main from the runnables.</div>

<div>Run stops when the runnables circular list is empty.</div>
<div>It then re-inserts irself (main) and continues.</div>

<div>In the case where an integer parameter is given, it runs</div>
<div>for the number of VM instructions. If there are still</div>

<div>tasklet is intercepted and returned as the result of run().</div>
<div>The idea is to either catch tasklets that went astray,</div>

<div>I don't quite remember what happens with exceptions.</div>
<div>Wel, I thing uncaught exceptions would stop run()</div>
<div>as well and let the exception propagate into main,</div>
<div>where you anyway suld put you default exception handler,</div>
