This is 2.6.24, and I previously used .22-vserver (not that this means
there can't be a new or longstanding defect or just lots of room for
improvement).

It's worse than you're thinking. When the submitter said "freeze the
system" I assumed it was the same thing I'd seen where aptitude takes
several seconds before outputting anything, and stracing it and that
point shows lots of read()s of large Packages file with descriptors
about ~15. That could reasonably make the system unbearable and not
useful interactively, but not completely unresponsive.
When I finally ran the given command, though, I got a very real
"freeze", as seen by the X11 interface. ICMP still responded, and the
machine recovers after ~10 seconds. During that interval, however,
the cursor is completely unresponsive.

I don't think it's disk IO related. Having run this command very
often, all my Packages files are cached at various layers, and
(despite having a not-recent machine with a slow disk and "only" 256MB
RAM) the drive heads seem to be inactive during this interval.
See the attached output of top -b -d0.5 -u root, that shows the
runnable/waiting processes (I did grep -Fvwe S to get rid of sleeping
ones). That's consistent with the submitters loadavg data. Note that
even with aptitude niced, all the other processes are starved.
I ran: sh -c 'while sleep 1; do date; done' and, during the
safe-upgrade initialization, got 21 lines of output, and 1 second
skipped (due to some combination of the effect of added load on
scheduling and perhaps being started very near to the edge of a
half-second line). That's the expected result.
Then I ran: sudo sh -c 'while sleep 1; do date; done. The result is
startingly different: there's now a gap of *21 seconds*. So it seems
that non-ptraced root processes are blocked, and others continue to be
run.
I still think there's some problem somewhere between apt and the
kernel. ptracing aptitude might reasonably cause a behavior change
due to scheduling or such, but that still leaves a fair amount of
observed behavior unexplained.
