Oh, and if you're thinking of buying a carrying case for your new ThinkPad T60, don't get the Lenovo messenger bag http://shop.lenovo.com/SEUILibrary/controller/catalog.workflow:item.detail?GroupID=38&Code=40Y8598 The strap is connected to the

OK, I have some question about the ktrace. The first notable call is the following: > 20188 MathKernel CALL mprotect(0xcfbc1000,0x1000,0x1000007) > 20188 MathKernel RET mprotect -1 errno 22 Invalid argument In OpenBSD, the only legal values

It appears that a similar bug was encountered by Debian in 2005. See http://lists.debian.org/debian-glibc/2005/08/msg00289.html http://lists.debian.org/debian-glibc/2005/08/msg00311.html http://lists.debian.org/debian-glibc/2005/08/msg00483.html
