Julian Elischer beef8a367c This solves a deadlock that can occur when read()ing into a file-mmap() ... space. When doing this, it is possible to for another process to attempt to get an exclusive lock on the vnode and deadlock the mmap/read combination when the uiomove() call tries to obtain a second shared lock on the vnode. There is still a potential deadlock situation with write()/mmap().
