Many thanks to everybody who replied, and everybody who thought about my
troubles.

The problem seems to be solved: I turned of Hyperthreading.  The gdb
build just finished after 5 minutes or so.

It makes sense.  When I was watching the "dual" CPU crawl from System
Monitor, I was struck by the symmetry: CPU0 usage went down when CPU1
usage went up, and vice versa.  Seems obvious now that I realize I was
looking at one dual-threaded core.  Similarly when the system locked
with both CPUs pinned at 100%, I'm looking at one core pinned at 200%,
or at a reporting artifact based on some impossible hardware state.
"Elementary," said he.

	Thanks again,		Mel.
