Something's wrong here. Running LTP's msgctl08 (specifically:
ltp-full-20070228) cripples the machine. It's a 4-way 4GB x86_64.
http://userweb.kernel.org/~akpm/config-x.txt
http://userweb.kernel.org/~akpm/dmesg-x.txt
Normally msgctl08 will complete in a second or two. With this patch I
don't know how long it will take to complete, and the machine is horridly
bogged down. It does recover if you manage to kill msgctl08. Feels like
a terrible memory shortage, but there's plenty of memory free and it isn't
swapping.
