--- Comment #5 from Cy Schubert <cy at FreeBSD.org>  2012-09-03 19:55:21 ---
Cy Schubert (cy at FreeBSD.org) here. I did try it with -d and -F (separately and together). It looped. I then performed the same under gdb and my results are as
follows:

^C
(gdb) bt
#0  0x342263bb in kevent () from /lib/libc.so.7
#1  0x33cb7d8f in iv_kqueue_poll (st=0x35857500, active=0x7fbfe944, 
    to=0x7fbfe93c) at iv_method_kqueue.c:150
#2  0x33cb77dd in iv_main () at iv_main.c:275
#3  0x33c9bfb2 in main_loop_run () at mainloop.c:735
#4  0x0804928a in main (argc=1, argv=0x7fbfea0c) at main.c:262
(gdb) c
Continuing.
^C
Program received signal SIGINT, Interrupt.
0x342263bb in kevent () from /lib/libc.so.7
(gdb) bt
#0  0x342263bb in kevent () from /lib/libc.so.7
#1  0x33cb7d8f in iv_kqueue_poll (st=0x35857500, active=0x7fbfe944, 
    to=0x7fbfe93c) at iv_method_kqueue.c:150
#2  0x33cb77dd in iv_main () at iv_main.c:275
#3  0x33c9bfb2 in main_loop_run () at mainloop.c:735
#4  0x0804928a in main (argc=1, argv=0x7fbfea0c) at main.c:262
(gdb) 

I haven't had a chance to look at the code yet but a spin-lock seems to make sense.
