</div></div>Mainly I'm trying to figure out how to map "kind of VM" to a file<br>
name. I just noticed that<br>
<a href="http://www.mirandabanda.org/files/Cog/VM/VM.r3058/" target="_blank">http://www.mirandabanda.org/files/Cog/VM/VM.r3058/</a> has a cogmtlinuxht,<br>
but not a cogmtlinux, VM. But there are both coglinux and coglinuxht<br>
and images, so it looks like MT and HT are orthogonal switches (on<br>
Linux, at least). </blockquote><div><br></div><div>Yes. And there is no such switch elsewhere. And ITIMER will eventually die the death.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
If they are, that's great, and I need to extend my<br>
existing kind-of-VM to reflect this, because at the moment it knows<br>
about :mt, :spur and :normal VMs, whereas it might need to know about<br>
:mtht, :mt and :ht VMs. Make sense?<br></blockquote><div><br></div><div>Yes.</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
