Yes.  Parsing the compiler output is done with multi-line regexps, and
these can take enormous amounts of resources (stack or heap as well as
CPU time) on compile buffers with lots of output.

You'll have to be more specific about what you mean.  If you're
looking at top, and expose an XEmacs window, then redisplay will take
up some time, of course.  XEmacs also uses internal timers to ensure
that autosaves are generated fairly soon even if the console is idle
(normally it counts keystrokes).  These should not take up much time
though, especially once the file has been autosaved once.

M-x list-processes.

C-h a process RET for an annotated list of functions and variables
related to processes.
