Hello,

I am checking out the bufdaemon code in kern/vfs_bio.c
One of the first thing the bufdaemon does is splbio()
then promptly enters into a for (;;) loop, potentially
waiting in kproc_suspend_loop(). Where does it lower
the cpu interrupt level so block I/O interrupts will be
received and the system can function?? 

thnx
-Chris
