Hmmmm, possibly related to the squake-1.1 segfault under 2.0.31pre9. My
squake segfault occurs _regardless_ of whether I specify "-nosound" or
not. It is not sound related. The last thing I see with strace is a couple
of "mprotect()" calls I think.
However if I load the system (ie. make -j), then squake-1.1 _will_ start
up and run fine. There is probably a race condition, either in squake or
recent kernels. As I have mentioned before, all is fine with 2.1.54, and
2.0.30pre2.

What significant mm and/or buffer changes have been made between early
pre2.0.31's and pre9??

Cheers
Chris
