Responsible-Changed-When: Mon Jun 23 10:44:26 PDT 2003 
Responsible-Changed-Why:  
I'll delete the zsh port ASAP to fix this problem.

State-Changed-When: Mon Oct 6 11:23:33 PDT 2003 
State-Changed-Why:  
The number of kmap entries has been increased, scaling along with 
maxproc and maxfiles.  As a result, panics caused by this special 
forkbomb should be a thing of the past.
