Hi Stefan,

Sorry for the delay in reply.

It was probably because I original put the new buffer in its own major
mode so I didn't use with-output-to-temp-buffer. I think a bit more
about this. I think eventually it will be good to have its own major
mode to have a few more key bindings. For example, I would like being
able to mark process for deletion with 'd' and 'x', or 'D' just like in
Dired. And 'RET' to visit a process buffer and maybe 'TAB' to move from
column to column.

Do you want me to change to with-output-to-temp-buffer?

I would say it is pretty close. I implemented the elisp version without
looking at the C source, and tested it with processes created by
make-network-process, make-serial-process and start-process and make
sure the output is similar to the C version. So this was done in Nov
2010 and I have been using it and haven't found any unusual things.

But I didn't follow the C version literally. Just before I sent out the
last email I did look at the C source again and felt happy with the
elisp version. It would be good for someone else to compare the elisp
and C versions.

BTW, I think list-processes is probably a third-class user command.
