c:\cygwin.disk is where setup seems to want to put the downloaded files.

No such problem here.

Right, I realize that.  When I was still working (now retired) I found 
/proc was a right useful directory.  In fact there was a program called
lsof which was supposed to tell you which processes had open files or
were cd'ed into a given file system.  This was to enable one to kill
the process so you could unmount the file system.  It didn't always
work so I wrote a script using /proc that fullfilled the purpose.

Question: is /proc implemented and I just haven't figured out how to
install it?

I thought of that and will certainly do that for experimenting but unless
cygdrive and proc need not be there it doesn't allow a restoration from
a tar file which would be nice.

I will experiment with that.  My background is experimental physics -
the emphasis being on the "experimental".  I just hope I don't kill
myself in the process  :-).

It certainly does - thank you.
