 Now that -current kernels are unbootable due to the problem described  
 in this report (the lack of the callout implemented by nfs), I've  
 been doing some tests.
 
 If I program a repeating callout with a timeout of 1, the system  
 works.  But it has to be 1, which is by pure chance the value that  
 nfs_ticks had.  Even using 2 does not work.
 
 The callout needn't do nothing special to keep the system up.  It  
 just needs to reprogram itself with the same frequency.
 
 At last, without the above workaround and when the machine gets  
 locked, nothing gets called; not even clockintr.
