It incresingly looking like somthing that would be very worthwhile.

That was certainly the conclusion as I understood it

I recon that with the XFILE stuff we now have in HEAD we should be able
to hijack the raw file descriptors and fddup() (I think thats the
function) stderr to them, rather than to /dev/null as we do at the
This will allow us to write a 'normal' panic action that doesn't need to
know about logfiles etc, but has smbd to the legwork getting it to
stable storage. If sombody gets to this before me all the better!
