I've put up a patch for stress2 from FreeBSD SVN here:

http://leaf.dragonflybsd.org/~swildner/stress2.diff

Please try it and report any issues you find.

Note a few things:

* I had to add the renameat(2) system call for it to compile (well we 
needed it anyway) so it won't compile on 2.6.3. I've put a patch for 
adding renameat(2) to 2.6.3 here -> 
http://leaf.dragonflybsd.org/~swildner/0001-Add-a-renameat-2-system-call.patch. 
You need to upgrade your system after applying it (do it either with 
'git am' or patch(1), doesn't matter).

* The information from the how-to about specifying free swap in 
stress2's resources.c shouldn't be necessary anymore. I've added code 
that should take care about that. Please check if swap space size is 
correctly reported if stress2 is run in verbose mode, since I just 
checked if it compiles but didn't run stress2.
