Also, INIT files can contain a resource of type 'sysz' id 0, to indicate the
amt of system heap they need.  The INIT 31 mechanism will grow the system
heap accordingly.  The resource contains 4 bytes with the amount of system
heap required.  I know of one instance where adding such a resource solved a
boot-time crash (ID = 25).&
