SVN rev 197930 on 2009-10-10 14:56:34Z by kib
Postpone dropping fp till both kq_global and kqueue mutexes are
unlocked. fdrop() closes file descriptor when reference count goes to
zero. Close method for vnodes locks the vnode, resulting in "sleepable
after non-sleepable". For pipes, pipe mutex is before kqueue lock,
causing LOR.
