Steam 'out of memory' crash afer leaving on overnight.

[robbiethe1st]

I left steam running overnight on my system, downloading Counter-Strike.
When I showed up today, I find this:

It seems to have crashed quite a ways in, as it was at 94% complete when I restarted steam.

I checked the minidump, and it seems to have data in it so that should help.
Note that I have 16GB of ram, plus another 24GB of swap, so we didn't run out of available memory space; we might have run out of 32-bit application memory space though.
