Hi
I got this on a netbsd-3 DEBUG kernel:
panic: kernel debugging assertion "(vp->v_flag & VONWORKLST)" failed: file 
"/dsk/l1/misc/bouyer/netbsd-3-1/src/sys/miscfs/genfs/genfs_vnops.c", line 1322

uvm_pageout() at netbsd:uvm_pageout+0xe1

any idea if this KDASSERT() here is right ? I've found other reports
of this; I suspect this issue may also be present in netbsd-4 because the
code path looks very similar. I guess the status of VONWORKLST can change
because GOP_WRITE() can block.
