More or less.  When I started learning Emacs, I began copying snippets
of code without really understanding how they worked.  Nowadays, I
still have a difficult time understanding some of them.  I've become
used to the facilities they provide, therefore my refactoring is a bit
at a time.  Not all of such code gets evaluated, though.

You are right about profiling: packages do exist which do a fine job.

Regarding tracing, I failed to explain, sorry.  I didn't mean such
kind of trace.  I was thinking about a logging facility, which logged
calls outside user control.  Such a facility, together with a profiler
and a call-tree generator, would have made easy tracking down the
function (or functions) which were causing the hang.

Nope.  I have submitted here the issue to experienced Emacs users and
they have not been able to help.  Thus it is not a matter of lack of
knowledge, it's just the lack of tools.
