Just tried the upstream tarball as you requested, and it behaves exactly
the same. My most vulnerable laptop (the Thinkpad) overheats and shuts
down within a couple of minutes.

If anyone else is running into this, I have found a way to mitigate
this behavior: start the client in a terminal with the -par=1 parameter,
ie.

	bitcoin-qt -par=1 &

Apparently par=1 limits the bitcoin client to just one thread, so it
can only max out the CPU on one core. This renders my Toshiba quite
reliable, and my Thinkpad often manages to not shutdown.
