Asking me? I don't know.<BR>
What sysutils does, sort of does. Right?<BR>
You know -- there is the exit code or the exit signal.<BR>
It seems to be using roughly (exit signal << 8) | exit code.<BR>
<BR>
I tried to "just" read the code (~ two weeks) but I might have read it wrong and I don't remember what I found, only that I meant to retain semantics, except for the efficiency of the wait.<BR>
<BR>
I don't think that explains the repacking though.<BR>
I have to read it again (again, again).<BR>
<BR>
That's what m3core was hiding, the exit signal?<BR>
I'll check.<BR>
