Hi all,

I can now confirm that these options (options DISABLE_PSE,
options DISABLE_PG_G) make the bug disappear.

I made 10 builds with (-j 10) to (-j 100) and did not experience
anymore any segfaults or illegal instructions.

Adding to it, I've not seen any pagefault with "make -j".
Without these options I haven't been abble to complete a
"make buildworld -j 20" without hitting a pagefault in pmap
somewhere. I thought that this would just be normal in a post
KSE world ! Sorry Julian ;-)

Martin
