Which swapfile.. I'm not very familiar with how memory management works...
I have a swap partition of size 512 MB (or so), and 1GB of actual memory.
The NORESERVE flag was not set in the mmap call that's breaking Steam... 
and it wasn't set in my test program either.

Here's output from free command right now...  it looks about the same 
that it did when Steam wouldn't run...
