Please disregard the Solaris bit as the 1.4.0 version of KQEMU is not
widely available there yet, so you can't use the SVN version of QEMU
with KQEMU anyway AFAIK.  I'd be glad to look at this in the (somewhat
distant) future and come up with a patch if anonymous memory on
Solaris is not stable.

But the Linux bit is still good to understand.  I know Fabrice put
this limitation in specifically because of problems with Linux
kernels, so it would be good to know what minimum kernel version seems
to have this fixed.
