You take the precaution of "assuming I have something explaining several
hundreds of MBs of memory consumption", and that's where the problem lies: I
don't have anything that could explain that.

Yesterday, at the time of the problem, I was simply checking in things in SVN
via VC-dir, that is buffers of a couple of tens of lines. Nothing else.

What's weird as well is that the memory shrinks back to a lower level -- even
if still quite important. No apparent reason for that. And, anyway, I still
can't use Emacs as you saw: I'm forced to kill Emacs from the Task Manager.

Now, what's complex, is that the problem is highly unreproducible: it occurs
sometimes a couple of times in a row, sometimes not for a longer period of
time.

And, I don't know if it happens with the current trunk as, yesterday, because
of the other problem (package not adding tex-site's dir to the load-path), I
was forced to regress to Emacs 24.3.1.

Best regards,
  Seb
