The problems with file truncation were not the SMP code, even though timing issues might make the problem worse. We still have a problem with the VFS layer (I haven't manifested it yet.) I am doing a careful code review, and found some places in the filesystem code where there are some dependencies on the v_usecount field of the vnode, and I think the current problem that I caused is somewhere around there.
