ce738c66fb Don't exit from watchdogd on receiving a signal if we cannot stop the watchdog. 
That'll require -KILL. This avoids resetting your system on one of the
watchdogs that you cannot disable.

33c9e87c89 Report any errors we might see when disabling the watchdog. 
Complain about extra arguments so people don't get surprised
if they type "watchdog 0"

5feb2d0d37 Pidfiles should be created with permission preventing users from opening 
them for reading. When user can open file for reading, he can also
flock(2) it, which can lead to confusions.

c053ae6d4f When disarming a watchdog by using an interval of WD_TO_NEVER a non-zero 
return value of the ioctl doesn't indicate that the command has failed
so don't let watchdog(8) return an error in this case.

if the swap subsystem failed.

134893e9ac Now that mlockall(2) is unbroken, use it to keep watchdogd(8) permanently 
out of swap.

743a7c42e2 Rename the WATCHDOG option to SW_WATCHDOG and make it use the 
generic watchdoc(9) interface.

Make watchdogd(8) perform as watchdog(8) as well, and make it
possible to specify a check command to run, timeout and sleep
periods.

Update watchdog(4) to talk about the generic interface and add
new watchdog(8) page.

3d5e7b3e42 - Add a software watchdog facility. 
This commit has two pieces. One half is the watchdog kernel code which lives
primarily in hardclock() in sys/kern/kern_clock.c. The other half is a userland
daemon which, when run, will keep the watchdog from firing while the userland
is intact and functioning.
