vmem_check_sanity panic

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

With NetBSD-current/amd64 of 9 Dec 2008 14:13 GMT, I just had:

panic: kernel diagnostic assertion "vmem_check_sanity(vm)" failed: file 
"../../../../kern/subr_vmem.c", line 1149

while build.sh -j5 on AMD athlon x2

I did get a core dump, but have yet to look at it...
