namei returns locked parent dir inode for create / unlink
...
don't hold fd table lock across idecref() (latter does block i/o)
idecref calls iput() in case last ref -> freeing inode
dir size is 512 * # blocks, so readi/writei &c work
unlink deletes dirent even if ip->nlink > 0

interrupts could be recursive since lapic_eoi() called before rti
...
so fast interrupts overflow the kernel stack
fix: cli() before lapic_eoi()
