I can see where the problem is, will make a fix in the next patch.
Other than the usual distractions, it took a few hours debugging due
to the large size of the trace when running aptitude (to see how to
get the information I needed). It seems that aptitude creates a _lot_
of windows (my first cut of a trace got 300Mb of trace). aptitude
would probably run faster if it didn't do that.
I would expect only a dozen or so windows in the initial program state; no
more than two dozen, tops. However, I am currently investigating a massive
resource leak in aptitude which leaked WINDOW *s among other things. That
might have caused what you were seeing.
That could be. I saw this happening during the initialization, had the
impression that it was creating the windows as a side-effect of reading
the package descriptions. What it looks like in the trace was lots of
calls to derwin, e.g.:
called {derwin(0x8262aa0,23,80,1,0)
_nc_makenew(23,80,1,0)
create :window 0x82657a8
return }0x82657a8
called {keypad(0x82657a8,1)
return }0
I cut the trace down by telling it to start when I was entering
KEY_RIGHT's, so that got past the initialization.
Anyway, thanks for looking into this; I'm glad to hear that it's probably
fixed :).
soon (next patch is a week from yesterday). It's definitely a bug in
ncurses though.
