cfengine watchdog is not biting

Hi,

At times the cfengine watchdog script is unable to resolve hanging 
cf-agents. the reason is that if the system is under high load the watchdog 
"hangs" because it reads his own stale pid file and is doing simply 
nothing. 

example:

i had 332 hanging cf-agent processe but the watchdog log just shows this.

Tue Feb 20 10:57:00 CET 2024 Initiating watchdog 6816488
Tue Feb 20 10:57:00 CET 2024 Aborting execution of watchdog 6816488, 
existing watchdog process 16450014 running
Tue Feb 20 10:58:00 CET 2024 Initiating watchdog 44499432
Tue Feb 20 10:58:00 CET 2024 Aborting execution of watchdog 44499432, 
existing watchdog process 16450014 running

after deleting the pid file...

Tue Feb 20 10:59:00 CET 2024 Initiating watchdog 25756150
Tue Feb 20 10:59:01 CET 2024 Found cf-execd not running
Tue Feb 20 10:59:03 CET 2024 Found 332 occurrences of cf-execd terminating 
unresponsive cf-agent
Tue Feb 20 10:59:04 CET 2024 Found 2 symptoms, threshold (0) breached.
Tue Feb 20 10:59:06 CET 2024 Initiating apoptosis
Tue Feb 20 10:59:10 CET 2024 Initiating anastasis

i guess there is room for impovement, as this can bring a system down quite 
easyily.
