The ChucKian watchdog looks for signs of shreds possibly stuck in infinite 
loops without advancing time.  Once it detects a potentially troubling 
situation (it has no way of knowing if there is actually an infinite loop 
or if the current process is simply taking too long), it takes measures to 
deprioritize virtual machine processes, reducing the likelihood of ChucK 
continuing to clobber the CPU.  In some cases, it may be desirable to 
disable the watchdog - the "--nowatchdog" flag should achieve that.

I hope this helps a bit.
